I read that the battery in the EVO 3D shouldnt be charging at any more than 4.2v, according to battery indicator my phone is charging at 4.331v right now. Should I be worried?
From car and hvac experience I would say no. Cuz voltage is always jumping around a little bit around specifications. For instance a car battery is supposed to be at 12 volts but jumps between 11-13 volts. So i would say that your have nothing to be worried about. Just watch the temperature when we start overclocking.
What have people's phones been charging at? Also the battery can get up to 41 C
When idle my phone is @ 3.75 V and while charging its @ 3.98 V. That's using battery indicator from the market with battery at 100 degrees Fahrenheit and @ 49% life.

Using Battery Monitor Widget, mine is charging at 4.34v right now. I don't think my Evo 4g charges that high, I thought it was around 4.1v. I will check when I charge that up later.
On the charger while using it, my phone got to 42C, and above 4.3V. Has me worried
I read something on here a couple days ago that said its normal for new cell phone batteries to become hot during the break in period. Didn't say how long that period was but I would guess a month. And why are you using celsius? That's just making this harder.
Update : 25 minutes charging now @ 4.1 V, 103 degrees F and 60%

I wouldn't be too concerned with the temperature getting to 42C. For it being on the charger, and you also using at the same time...that's not too bad. I've had mine up to 45C when charging and using it. With my Evo 4g, it would get up to 47C sometimes while charging and tethering over 4g at the same time. I never had an issue. The phone has safety features implemented so that it will stop charging if it overheats. I'm not sure what the set point is for that, but when it's activated, you'll get an amber and orange flashing led light. That's letting you know it's too hot.
Haven't looked in to this issue at all on my phone, but come to think about it I do have something weird when charging.. Once the phone fully charges up and hits 100 percent it stops charging. I know this is a safety feature kinda thing but it would hit 100 and then the battery indicator would just show normal while it is still plugged in, and also the battery percentage would drop while still plugged in. Is this normal or no?
A few thoughts here:
1: 43 (Even 45) celsius is NOTHING for electronics. Hell, 50C is 122F. That's about how hot a car will get sitting in the sun on a 95-100 degree day for about an hour. Your cars electronic parts don't get cooked, do they? I read somewhere Lithium Ion batteries can handle up to 60C internally (140 F), and that's safety restraints, which means it's been lowballed. Your phone wont melt from the battery.
2: Yeah, it takes a few charge cycles to set your battery in. It'll run hotter than normal till it does. Think of it like a trampoline. Fresh, brand new, it's hard as hell to bounce on it cause it's so tight. However, after a while, it stretches out, and it's much easier. (Dirty minded people can stop laughing now) Same with car engines, subwoofers, etc. They all have a break-in period. The battery takes about a week to settle in, from what I've noticed. Mine ran hot for the first few days, and it's fine now.
3: 4.325 volts is within 3% of the stated 4.2. It's within the margin of error... But it should also be within engineering tolerances. If the guy who designed the phone/battery didn't allow for a 3% margin of error, he should be given an award for "Worst Engineer of the Year"... It should be 100% fine. Like the poster up there said, 12 volt batteries in cars can range from 11-13 (Id go so far as to say 10-14) and still operate the car 100% effectively. Also, you would NEVER get a full charge into a 4.2 volt battery if you put 4.2 volts into it. You've gotta have a higher voltage on the outside to force a charge into the inside (High school stuff I learned, so I may be a bit rusty)
4: To :Winning:, Yes, it's designed to charge like that. It gets to 100%, and sits there not charging. It will then drain down to 90% or so, and charge back up to 100, over and over. The OG Evo did this, (Albeit not as well) but the battery widgets wouldn't display it. That's why the Evo would drop 4 or 5% in the first 5 minutes of use. You would unplug it, and then the phone would query the battery and figure out that it was really at 95%, and display it correctly. It wasn't really draining 5% of the battery instantly.
5: Yes. Red/yellow flashing light = overheat. You can probably make it do this by sitting it in a parking lot on a 110 degree day in Arizona while charging it and leaving it face down on your dashboard for an hour. You won't fry it in your house unless you have a bad charge cable. A bad charging cable is the ONLY potential source of worry I have about overcharging/overheating/etc. 2$ Chinese chargers don't have any fail-safes installed in em usually. You have a 500$ phone, don't skimp on the thing that connects it to 120 volts of instant electronics death. (Or 12 volts, in the case of car chargers. But that's more like a slow, smoldering, smoky death)... It'd be like not using a condom with the one night chick you met at the bar. You don't plug your you-know-what into ANYTHING unless you know it's gonna be safe
Thanks I've mostly been using the HTC charger. I guess I'll stop worrying

Interesting observation.
Wasn't concerned about the voltage, but was watching the heat level.
With live wallpapers: +10C addition.
My charge temp is 33.9C without.
My charge temp was 42.8C with it.
Guess it'd be kinda hard to cram in a cooling fan for the graphics chip!!! hahaha

There seems to be a debate on this topic as to whether you should do a FULL drain on your battery and I wanted to know what people's thoughts were on this in this forum.
I've used my phone twice now to the point where it has auto powered down on it's own. I will then hit the 'Power' button to ensure that battery is truly at 0% (the capacitative buttons blink for a second to confirm that I've hit the power button but there is no more juice left to turn the phone on).
I will plug into the wall charger and allow it to charge for 4 hours (usually around 4 hours, I'll check back to see and hit the power button and the onscreen battery display will show 100% charged).
I will unplug my phone, power on and keep using until the phone fully drains and powers off on it's own again before repeating this cycle.
However, others have stated that this is NOT necessary for Lithium Ion battery and can actually damage the circuitry of the battery? I've always been under the impression that you need to do a complete & full battery drain for lithium ion batteries at least 3 -5 full cycles/times before the battery has been conditioned/optimized for capacity.
Maybe I'm wrong...after all I'm coming from a G1 and this practice helped my atrocious battery life on that dinosaur!
If this is wrong, when should I be plugging my phone back in to charge? When it gives me the first warning to charge in (battery level turns orange - I assume this about 20% battery left) or on the "critical" battery warning when the battery icon in the notification panel turns red (assuming this is about 10% battery left)?
from what I've read in the past, letting your phone drain completely down until it shuts itself off is not good for the battery. I could be wrong but thats what I've read

Yeah, I've heard both sides and I've conditioned my battery for the G1 because it seemed to drain faster if I plugged it into charge when there was 30% or so still left.
Well, I've done two complete cycles so I guess I'll just try recharging when it hits the red mark next time.
When you plug in to charge? Orange, red or whenever to top off?
i plug my phone in when i go to bed. I dont care what the battery is at. I also charge it while i'm at work so when I leave, its around 90-100%. My battery rarely reaches red.

LOL - that would prematurely killed my battery capacity on the G1! I went thru two batteries before I started draining all the way down. Made a difference between 4-6 hours and 6-10 hours.
Seems like this phone doesn't need to do that tho.
But what're you getting on average for battery life and display on time then?

I do the exact same thing. First with my Captivate and now with the SGS2 and the battery life on my captivate held pretty much exactly the same charge for the entire 15 months I used it. The battery on this SGS2 seems to last about 150-175% of the Captivate battery under the same conditions. I just came back from a week on the road where I spent 9-12 hours a day away from a charger and was using my phone constantly all day long and would get back to the hotel room with 30-40% battery left. Considering I was listening to music, playing plants vs zombies and sending and reading push email constantly throughout the day I am very satisfied with the battery life on this phone. I've never done any kind of conditioning or special battery maintenance.

i stopped looking at my battery stats a long time ago. I'll peak in there once in a while but I dont really care what the stats show because I'm always around a charger. As long as I get through 12 hours or so without charging, i'm happy.
Some devices need a full drain cycle to properly calibrate the fuel gauge - ours does NOT.
Lithium ion batteries don't like deep discharging - in fact discharging them too much will permanently damage them (fortunately, all batteries sold to end users have built-in protection chips to prevent overdischarge - but do you REALLY want to rely on that chip?)
Similarly, they don't like charge being forced into them - so don't "bump charge". (Bump charging is removing and immediately reinserting the charger when the phone says charging is complete.)
For long-term storage, store them at around 50% capacity if not being used. LiIons that are stored at 100% charge lose capacity MUCH faster than ones stored at 50%.
A Li-Ion that has been sitting for a long time (months...) will develop a passivation layer that can be detrimental to performance - a few charge/discharge cycles will fix this. You don't need to do a full discharge/recharge - probably even from 90 to 70 and back up a few times should be fine.

what about short charging during the course of the day? For instance, while I'm at work, I like to plug it in for a bit and then use it off the charger. Then before I leave, I charge it again for a bit. Do you think thats okay to charge the phone for short ~1 hour bursts?
No, the battery itself doesn't do well with deep discharges, but every device with one has circuitry to manage this and keep it from happening. The phone will shut off before the battery reaches a critically low discharge state. Just as it will cease charging before it blows up. Just because the phone shuts off does not mean that the battery is too low.
Assuming the phone has the proper cutoffs, it's not really any different to do two discharges to 50% or one to 100%. There have been studies that say leaving it on a charger is bad, doing two 50% cycles is worse than one 100%, etc. I've always just trusted that the phone manufacturers design the battery monitor and control circuits correctly and not worry much about it. And I've never had to replace a battery yet and always get acceptable life.
It's lithium ion, not nickel cadmium.
Full drains are bad for lithium ion.

lithium ion batteries dont like being under 30%. and they also dont do well if they are kept at 80 percent or above all the time. for longest battery life don't just let it sit on the charger all day after it fully charges.
I agree with Mikey here.
Also, batteries take charging current better (less wear) at lower states of charge. That's why I put a variable-current charging algorithm into my Infuse kernels (charginghacks branch on github)
800 mA at low voltages (200 above stock), dropping to 550 near the end (50 below stock).
Unfortunately, charginghacks is likely not going to be possible with our hardware. One of the differences between the I9100 and I777 is a different battery charger circuit - ours is far less flexible.

This phone actually charges with the screen on though, so it's not like the Infuse where the battery would drain with the screen on and the phone charging.

Infuse would charge with the screen on - but not if the screen was on AND the CPU was cranking.
(worst-case was navigation at full brightness - and I've seen reports that the I9100 also has the same problem.)

When web browsing, playing a game, or other general use late at night I'd plug the Infuse into the charger. It would still drain. Doing the same on the SGS II and it at the very least maintains it's battery level, so it's a drastic improvement over the Infuse.
I've had my new HTC Amaze 4G for 4 days now and absolutely love it, what a great phone! The battery life is great (I'm careful with all my settings) and I'm only finding issues with the charging TIME.
It's the second time I've charged it and after noticing how excessively long it took the first time, I clocked it this time and it took 4 hours and 45 minutes. I used a charger that I've used on many other devices with no issues (5 volts 1 amp).
The battery level increases 1% every 3 minutes, which adds up to 5 hours. I calculated this both with the screen on and by averaging out over a longer period of time with the screen off. I also tried with the phone completely off and the results were the same.
I made sure there were no processes hogging up processor time or excessive RAM usage.
When I go into to "Settings -> About Phone -> Battery" Battery status clearly states: Charging (AC).
I have also read somewhere that this can possibly be set this way by design (possibly to prevent the battery from heating or overcharging and saving its life in the long run).
I also realize that the phone is new, and the battery needs a few charges to be settled, but 5 hours to charge on the second charge just seems like too much.
On the HTC product support website, on the faq there is the following question/answer:
How long should it take to charge my battery?
"Your battery can take up to 4 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function."
Can anyone out there with an HTC Amaze 4G confirm how long their phone takes to fully charge from the AC charger?
I'm thinking/hoping this is a defective device/battery/setting...I don't like having to wait 5 hours to have my phone fully charged.
Thanks in advance,
Filipe
Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks
Come on....anyone? Please? This is driving me nuts!!
Yeah that sounds about right. Don't complain man. Your battery life is pretty good compared to other devices. My device takes 3 hours to fully charge and can last 24 hours with minor use. Just charge it when you go to bed and you won't notice the time it takes
My desire hd takes almost as much (Around 3 hours) and my Optimus 3d prolly takes even more (5?) to fully charge from a full discharge...
(With Stock HTC/LG Charger. The HTC's AC Adapter is 5V/1A [Shouldn't that charge a battery in under 1 1/2 hrs?]. Not too sure about the LG)
They take Much longer to charge on Computer/Laptop USB Ports. The Optimus 3d actually loses battery while charging (With screen on) with a USB port.
Also, 5% a night is pretty good. My desire hd goes down 3-5% per night (2g, no data enabled.) or 0-1% with Airplane Mode. (Rooted, Revolution 6.31)
And my optimus 3d pretty much runs out of battery in <100 mins with full brightness while Playing Games - It goes down more than 1% per minute depending on the game being played, especially if 3d Converter is used. This is pretty much the same for all GB/Froyo ROMs.
Just charge it when you go to bed and you won't notice the time it takes

I Agree. Both phones usually last around a day at least for me. You could always try a battery monitor such as GB Battery Stats or watchdog (The CPU One). CPU Intensive applications and Awake time during sleep are usually what cause bad battery life. Faster chargers such as 2A ones should also charge the battery faster, but they might reduce the overall battery life.
I would suggest buying a wall charger and cheap batteries from ebay. They last almost as long as stock batteries and cost only ~$2-4 each. [They apparently explode though. Never happened to me.]
-------------------------------
Both phones seem to charge from 0-90% much faster than 91-100% as well. I'm not sure why, since 100-90 wastes just as fast as 90-0. (Charging from 90%-100% battery practically takes a third of the full charging time)
many thanks
RESOLVED (Sort of...lol)
Thanks for your feedback guys!
I just finished charging it this morning, and it's FASTER NOW!
Took exactly 2 hours and 37 minutes (Battery Moniter is a great app!).
I think it actually may be due to the phone having some sort of smart charging system which "looks after" the battery. Since the phone is new, it might be wanting to start it off with some slowww charges and gradually speed them up.
But I still have to narrow it down some more since this time I'm actually using the supplied cable and charger (the ones I tried before were also 5V/1A).
The cable I was using (had it for a while now) had a pinch or two, it didn't look that bad, but I'm thinking it could also be the cable (could be shorting)!
I'm gonna do some testing on this cable now and report back my findings!
Thanks again!
RESOLVED!!!
Ok, so it actually turned out to be the cable. I really feel like a dumb ass...lol. Oh well, at least I figured it out!
So yeah, one good way to see if your cable / charger is good is to use Battery Monitor, and on the main screen where it says your device is charging (AC) and etc..it will also say the actual amperage (in mA) being fed to the battery...that number should be within the 500 to 750 range, if its lower, there is likely something wrong. (Mine was at 16...lol).
Thank you all for your help!!

My problem was the cable, and it was causing the phone to take five hours to CHARGE, not discharge.
These phones don't hold charge for too long, and the more activity you got going on, the more power it will consume. The screen hogs up the most power, so using the device constantly (especially with high intensity background light) will drain the battery very quick. First smart move would be to set the screen intensity to the lowest setting. Wi-fi and bluetooth, if you're not using them, shut them off. Open your task manager (or get a decent one from the market) and kill all the apps you got running in the background.
Games also require a lot of graphics/processing power, so naturally they will drain a lot of battery too.
Edit: There are some special cases where it could also be related to your network or even simply coverage zones exposed to the device. If it's stuck in a zone where it has weak 4g and 3g signals, it will keep bouncing back and forth causing more drain than normal on the battery as well.
If you've taken all these things into account, then you may have a defective device, then you will want to setup an RMA...or just take it back wherever you bought it and ask to exchange.
Hope this helps,
Cheers
My skyrocket takes about 3.5 hours to charge from 10% to full charge. If I plugged it in the car charger and run google map with the radio on the background, it would slowly drain the battery even though it was plugged in. My iphone 4 did not do this. It charges very fast and does not drain the battery even when I had several apps running in the background. I think the skyrocket consumes more power whether it is plugged in or not.

Hi, what you need is a charger with a higher amperage rating than 500mA (or 0.5A). Buy a charger that is rated for 5V/1Amp like this one and your problems should go away.
The phone is basically "burning" more energy than it is receiving from the USB charger, hence the discharge.
To know the amperage rating of your charger look on the label for numbers that look like "5V/500mA"...
Hope this helps,
Cheers
EDIT: The link I provided does include an iPhone cable, but I'm just referring to the charger itself, the cable would obviously have to be a micro-usb.

thread moved to...mexico?
Most illegal threads are trying to move from Mexico.
But, you need a charging source more powerful then the base 500ma, (or whatever that term of measurement is) computers are only supposed to supply 500ma to a USB port so AC adapters are typically better for charging. But feel free to follow the post above and check the rating on the charger.

I think I know what the problem is: Your phone is trying to kill itself and save humanity from that terrible font
seems like a bit much but it could be normal.
Once your phone's charge reaches 100% it stops charging to prevent damage to the Lithium-ion battery. I am not sure however when it starts charging again.

Mine will charge AND increase while using it in the car with GPS running (huge battery drainer) and a driving DVR program (DailyRoads Voyager) and the screen on. All with a car charger and cheater plug that shorts Pin 2&3. That's the secret to getting rapid charge to work. The OEM home charger has those pins shorted internally. If you are trying to charge over USB on your computer then again you need that cheater plug and ensure the USB port can support more than 700 mA. If it's a USB 3.0 port then it should handle that current.
No problems for me on the stock or aftermarket chargers with the screen on.
I have the same problem with my brand new I717 GN. Battery level slowly drops when on charge, even if it's the OEM wall adapter. I've tried my Kindle USB cables as well with about the same results. I noticed the charge is a bit stronger from the wall source, but still can't keep up with even simple web browsing via WiFi. I've installed JuiceDefender as well, and it's helped reduce depletion a bit, but not really enough. This phone would never last me a full day of intermittent use without a power source.
I've read several of these threads and there doesn't really seem to be a solid solution to this other than some GN owners saying they have the problem and some don't...
Someone mentioned a crosswired 'Smart Adapter Compatible with Samsung Galaxy S' on Amazon (I'm too new and can't post the link)... I might try that but maybe I'll return for a new one if some people don't have this battery problem, unless it turns out to be a latest firmware problem..?

he mentioned it and linked it 2 posts above you
ive thanked him, and guess about to buy
just that shipping cost more than the item itself, sheesh
I read an article in a journal recently about how smartphones charge their batteries. The article claimed that once the charge has reached 100%, it will stop providing current to the device until it reaches 90%, after which it will then trickle charge to maintain it at about 90%. All the while the battery meter will still show 100% (at least in the case of iPhones), but after you unplug the phone the first 10% will go rather quickly as it approaches the real charge level.
True for our notes? No idea. But with how Lithium batteries work, I wouldn't be surprised.
I haven't gotten my Note to discharge while plugged in with the OEM AC charger. In the car however, running Waze will suck the life out of it even while charging. (My car charger puts out about 150mA less than the OEM AC charger). Oddly enough, running Navigon on battery alone has less discharge than running Waze while plugged in...Which sucks, because while Waze has crappy directions, it has saved me many hours by routing around traffic. But at least the phone still charges while using Navigon and streaming some Pandora.
I know it sounds weird but it's hard for me to ignore the fact that whenever I charge my phone early in the morning, battery temp - 26C usually, around 4 AM it charges like all hells gone lose. From 20 to 100 in somewhat an hour or more.
Note, my phone is a standard non fast charging/dash charging phone which Ampere reports the maximum current the chip let's into the battery is 820 mA.
If I charge the same phone after some usage when the battery is at 37-40 C it takes around 2-3 hours to charge from 20 to 100.
Does any one here had a similar experience?
Off-topic: Why do phone companies don't make water cooled phones or phone covers?
I keep reading that you should try and just charge your phone to 80% to help keep the battery healthy, as going to 100% can shotren the life span of the battery.
How ciritcal is this?
I know letting your phone run down to 0% is bad as it takes a fully clylce then to get back too 100% and this is not good for the battery long ter, but i must confess i usually let my battery get to around 50/60% ish then charge back up to 100%
I've always charged my phones fully and never noticed any issues. Maybe if you plan on keeping a device for 10 years, but for the usual lifetime of a phone it's just fine. My OP7 is 2 and a half years old now and still has 86% battery health. I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

Hehe yea, I guess they all show 102% then because I have that as well
I like the adaptive charging, set up your bedtime and alarm for getting up (or turning over) After bedtime, phone gets trickle charged to achieve 100% at morning alarm. No excess heat etc. Phone then lasts me all day till bedtime when put on airplane mode, switch off Wi-Fi, & sleep. Works for me.
I'm showing 106%
I always charge to full, using adapting charging over night. Charging slowly and keeping temperature down is more important than keeping it to 80% from my understanding.
I just lay my phone on a slow charge Qi pad every night and when I get up it is at 100%. Nexus 6, Pixel 3, now Pixel 6. Perhaps my battery life went down a bit on my Pixel 3 after 3 years, but not enough to notice. I think 100% charge (at least slow charging) is safe for 3 to 5 years of battery life.
Li's like frequent midrange power cycling; it can extend the lifespan hundreds even thousands more full charge cycles.
Voltage and temperature are the Li's biggest stress factors. Low or high temperature charging can cause Li plating.
The higher the cell voltage, the faster it degrades.
The same is true with temperature.
Personally I just replace them every year or so as a failed Li can severely damage a phone. They tend to swell during a failure which can easily damage the display.
My Samsung S10+ is 27 months old now. I'm charging it to 80% mainly daily. Had maybe max 20 full charges and only once or twice to zero. I'm at 86% battery health (according to 146 sessions). Was 92% six months after buying brand new.
I think it helps. Also since the battery is OK (4100mah), dont need that extra 20%.
EDIT: 15W Samsung "fast" charging. As fast as that is ...

A Li is considered degraded when it reaches 80% of it's initial capacity. This signals the end of its useful service life.
Degraded Li's are more likely to fail.
Trust me it's better to replace it before it fails...
I think Better Battery Stats made that reco back in the day.
Charge to 80% and plug in at 10%.
Not so sure that really matters anymore though.
Both my 2 XL and Pixel 5 were plugged in before bed, unplugged when I got up, plugged back in when I hit 10-15% or when I went to bed.
If you plan on keeping your device for a long time (like 3-4 years) doing the unplug at 80% and plug in at 10% might make a diff.

10% is too low. It causes a lot of stress on the battery as it drops below 20% to charge from that starting point or lower.
Worse there's little usable energy after 20% because of the lower voltage. The phone uses the same wattage which is determined by V×A=W, so as the voltage drops it needs more milliamperes to make the same wattage. The discharge rate increases as the cell voltage drops.
A better low cut off is 30-40% or even higher and a high cutoff of 80% although 62% is optimum.
The Li likes frequent midrange power cycling. Charging beyond those parameters is for your convenience at the cost of battery lifespan.
Batteries are cheap and most are easy to replace... so I don't sweat it.
I expect a service life of 1-2 years on a heavily used N10+ battery.
However charging in the 40-72% range yields the most rapid fast charge in the shortest time so it makes sense to use this whenever convenient.
Well, I know things have been updated within Googles code itself.
"Adaptive Charging" / "Adatptive Connectivity" additions.
This was a real big problem for me with my HTC 10, (2016)
Battery degradation threads starting popping up.
I installed Accubattery after 1.5/2 years of owning the device and the battery was degraded to about 77% capacity at that time, IIRC. I was charging to 100% at that time, also.
So, I began charging stricly to 80%.
Compared to my HTC One M8 that to this day still has 90% capacity, and I used that device from the day Verizon released (3/2014) it until the day Verizon released the HTC 10 (5/2016).
I somehow managed to use the HTC 10 up until I bought the Pixel 5 on release day (10/2020).
I was charging the HTC 10 like 3 times a day just get through, and even went back to the HTC One M8 at one point because I had enough, but was waiting for the P5 to drop.
So to answer the question, I do believe it helps.
I do think that Adaptive charging/connectivity help, as well.
I take the view that if I don't need all the capacity on a particular day I charge no higher than 70%, which lands me around 30% end of day. Otherwise I'll guestimate what I need. Off to take some photo's tonight, so will probably charge it to 90% or so.
If you like fiddling around you can use something like Tasker to switch a smart plug that your charger's plugged into on and off at what you consider appropriate battery levels. Makes it all painless once set up. Or you can buy some extra hardware too. I use this in my car to limit the phone's max charge and temperature as, for me, I think most and fastest damage is done in a hot car float charging the phone at 100%.... https://chargie.org/ Not cheap but ok in my mind to hopefully extend the service life of the phone's battery. Less than the cost and hassle of replacing a battery anyway! (I'm not associated with Chargie other than as a customer)
OK, admittedly off-topic, but, this kind of sounds like a variation of the guidance I use for charging my electric car. Don't charge it unless it drops below 80% (so don't keep topping it up), but don't let it go below 20% regularly either. I mostly plug it in at around 60% and let it fully charge. Given the cost of a replacement battery would be more than the total value of the car, I hope this gives me 10 year of life.

EV metering is set up differently. What shows as 100% is likely a conservative 80% charge. Research for that variant.
A 35-40% low cut off is probably better as going lower generates more heat causing needless stress... unless you need that capacity.
Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.
I’ve never had any problems charging to 100% before so I’m not stopping now. I’ll be deleting this app if it keeps warning me like it has done.

Hello, I'm using a pixel 6 with two cards sim. When I go to sleep the phone is fully charged and internet/wifi is turned off. When i wake up i have 88% battery (I lose 1,5% per hour). In battery use i see Ims Service. I did a test and in...

I used to cycle from full to empty on my Pixel 2 before recharging, at about 3 years the battery couldnt last until lunch anymore. This meant more cycling, and I could fully discharge/recharge it 3 or 4 times a day. Within 6 months the battery only lasted 5 minutes, it was stuffed. Phone always hot and needed to stay on a charger 24/7, would turn off if I opened the camera without usb power connected.
Held out about 6 months on a permanent usb battery bank, was such a slog to wait until the Pixel 6 was released.
