Has anyone checked the ROG phone "Battery health" on AccuBattery Pro? Mine is showing Estimated Capacity as 3,548 mAh, Design Capacity 4,000 mAh. I completely discharged then charged to 100% as calibration. Brand new phone.
Mine is showing 3,531mAh after around a week of usage.
Someone should report this on the Asus forums
mine also show 3500mah after 2.5 weeks of use
I have posted this issue on ASUS's Forum
https://www.asus.com/zentalk/thread-249329-1-1.html
Please feel free to add your battery capacity screenshots on their forum so we have a reference for the future
Mine's at 3462 after a little over a month. With a health of 87%
OK, then. We shouldn't be concerned. The proper way to measure battery is more complicated than what AccuBattery does (the proper way involves measuring battery discharge at a controlled rate). Since many of us are getting similar readings on AccuBattery, it's probably that AccuBattery's method isn't accurate.

Same here: 3536 mAh 88% health with Accubattery first charge out of the box after discharging to 15% following first power up.
Either Accubattery has a problem with our phone, or Asus is ripping us off.
If the batteries were bad, we'd all have different readings.
I am guessing the AI charging might affect the measurement from AccuBattery. However I also don't think the battery capacity is full 4000 mAh. My last phone from Motorola has a 3000 mAh battery on the spec chart, but the battery itself prints 2810 / 3000 mAh (min/typ). From the ROG phone tear down videos, this battery isn't marked though.
From the asus zen forum the only solution the person provided was to bring the device to a service center to get it tested
I maybe wrong however with batteries these days it only ever uses a percentage so that there is redundancy for failure and to preserve the battery life.

Samsung does that. Note 9 is 4000mah but Accubattery says 3800mah on new phones. Every one of them.
Power reserve to not kill the battery early.
Anyway, 3500 mAh seems like one heck of a left over reserve.
Our batteries should last 5 years at least
Same "problem" here, but maybe it is because program has small amount of gathered data about battery usage. I did full discharge and full recharge yesterday, and goz about 3567mAh, but ill try to calibrate battery and use measuring app for longer time to get more accurate results.
Ps: I am using only slow charger to avoid overheating to eliminate battery damaging when recharging
I have not checked my ROG Phone in any 3rd party apps as I have not had a reason to question the 4,000 MAH
It is not a problem, lithium ion battery deteriorate faster if kept fully charge all the time or when discharged to low. Since most people have the bad habit to plug their phone all the time and keep them full for a prolonged period of time, oem have to be creative to fight this. Some will show your battery is charged at 100% while in reality its only charged at 90% .That is what your program most likely reading.
lithium ion should only be charged at 100% before you leave the house, i tend to keep mine between 50 and 90 usually . With quick charge there is no reason to keep a phone plug overnight, 10-20 min before leaving the house is plenty.
I have turned on AI for battery charging and as soon as my Battery reaches 100 it stops charging which is good enough for me to have faith in the charging technology in the phone and battery capacity.
I do leave mine plugged in over night however with the right equipment to check its hard to get a good understanding of whats happening. Theres inbuilt battery health tools so i would always advise using these and going through the features of this over 3rd party jank applications and trust them. Its the only tools Asus are going to support in any diagnostic troubleshooting.
Hi guys, I am returning after some time of usage and charging. After some charging cycles I have to admit my battery capacity is "increasing" - well better say, it is getting used to be charged properly. Now I passed 7 full charging cycles, but after 3rd one every next charge had more mA. I started at 3479mAh with full battery, now I ended with 3711mAh - hope it gets even better (I'll be glad for at least 3800, but who knows?). Everytime I tried to charge only when I was below 3%.
I have to say I am using slow charger with 5V and 400mA current. Battery checker from mobile manager was not detecting any issue with this way of charging nor AccuBattery Pro. I also know, that batteries shall be charged only about 80% of its capacity, but I am still sceptical about that rest 20% so I am charging to max everytime.
Hope I helped...
...another time passed and I am back with another results. After a lot chrging cycles I am stuck at between 3500-3700mAh of total capacity. I was searching around whole internet and found out, that phone manufacturers are "decreasing" battery capacity with SW at 90% of total capacity to prolong battery life and avoid battery wear, because everytime you charge the phone, you think you are charging to 100%, but in real you are charging to 90% only - rest of 10% is "hidden" to save your battery life - due to my calculations and testing it might be true. Anybody else had something different, so we can compare it?
I've just started cycling with accubattery will post when I get some solid data but seems battery has lost some capacity already only had it since November 5

Hello everyone,
Getting my G2 tomorrow ad was wondering what's best to do for the initial charge ?
What did you all do and how do you find your battery because of it ?
Cheers James
hi there mate
I did a 3-4 hour charge until the battery was fully charged...the orange led charge thing goes green and its fine then
right now im managing to get a day with heavy use, which is good
Thanks immya
Any other advice please ?
I atcually do the same. But i repeat the process of fully charge and discharge the phone completly about 2-3 times. So the battery gets well trained. I repeat ist about every 2 months. I know it should not be relevant with those new batteries, but i found out it is, and the battery last longer.
jut my 2 cents
Cheers,
Chaos42
it's 2009, just charge it and use it.
when i got mine the battery was ~1/3 full, i charged it till ~2/3, then had to leave and completed the initial charge like two hours later, all works fine, getting somewhat between 4 hours and 3 days of usage.

no, what i meant was what immya just said. that with the modern Li-Ion batteries you should not worry to much about how and when to charge. I just wanted to add that even it is 2009 i observed a far better battery lifecycle and stamina when you try to take care of your batterie. and charge it as decribed. that's my experience. at least for the initial 2-3 charges.
cheers,
chaos42
not that i am trying to discredit you here (in fact i would be very interested in such numbers myself), but did you do any tests or comparable setups to check the difference? because if we are talking about "a feeling" that you have this is IMHO not really relevant data. i would like to see two identical phones in a (at least) similar environment, performing the same tasks the same amount of time a day, and with that getting different runtimes on the battery for a period of a few weeks. these two phones don't need to be heros necessarily, as long as they have the same type of battery and can produce comparable results, but as long as this doesn't happen i myself rely on the tone on li-ion batterys in general. which is (and i am not able to quote or prove this): they are robust in terms of regular charging, and worrying about wearing the batterys in or training them isn't worth the effort. again no discredit here, but as long as no comparison has taken place there is effectively no data to analyze... just too much variables.

NiCad batteries work best when fully discharged before re-charging otherwise you get what is called the memory effect. If you are in the habit of topping up before being fully discharged the better 'remembers' how much you let it drain before charging it and then get's the idea somehow that this is what its capacity is and goes flat at the point that it 'expects' to be recharged.
NiMH batteries are much less prone to memory effect. They are the ones that need the 16 hour first charge then subsequent charges are shorter.
Li-Ion - lithium to its friends - are not supposed to suffer any memory effect at all. You are supposed to be able to top up as and when you want without any detrimental effects.
None of the above batteries will last forever and will need replacing after 2 or 3 years of daily use.

Absolutely spot on!
These days batteries do not require dishcharging fully before recharging. Even if the person in the phone shop says "ensure you charge it for 12-14 hours before you use it", this doesn't matter - once the battery is fully charged, it stops charging itself anyway - even if you leave it plugged into a charger!
Same as what's being said already.
To add, it's even better to keep your lithium battery topped. Fully discharging them is actually bad for a lithium battery. Full discharge and heat is what's bad for a lithium battery.
For a nice reference, check this: http://electronics.howstuffworks.com/lithium-ion-battery.htm
(the life and death part is what might interest you)
On a more interesting note. A long long time ago I got a MDA Compact aka Qtek s100. And there was a lot of debate here on the forums about the initial charge. In the manual it was stated that you should charge it for like 12 hours or something the first time. Then people obviously also said that was bull, because it had a lithium battery.
But! As for WM2003 it didn't save it's whole registry etc on the ROM but in the RAM. Once the battery was dead, bang! hard reset right there.
So they included a little NiMH battery in the s100 that would keep the RAM 'alive'. And that was the reason it needed such a long first charge, for the NiMH cell.
And for some reason a lot of manufacturers take an 'old' manual text for the first charge of a battery. Although that doesn't happen that often anymore. Especially in the beginning a lot of instructions of how to use a lithium battery were just plain wrong. And they put NiMH or even NiCad instruction in there!
Edit, some instructions as found here (http://www.batteryuniversity.com/parttwo-34.htm). Talks about laptops, but it's the same nonetheless.
Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

So I have had mine sitting here all packaged up since tuesday.
And im looking to now actually open it and play with it,
Do you recommend I charge to full when off, or on? Perhaps run it dry and then charge it up?
You used to be told, Charge it for 8 hours before you use it...
That surely can't be true of todays rechargeable battery technology?
[Q] charging and battery damage
If I leave my touchpad on the touchstone charger for long periods and the touchpad is switched on will this damage the battery?
I know I have had laptops and always ran them of the mains and the battery has stopped holding a charge.
Cheers.
I assume that the touchpad has a charging circuit that stops it charging when the battery is full, but batteries will always fail after a while regardless. Lithium batteries are best charged often and not let run down too much in between.
Also, dson't let a lithium battery run down completely, you can significantly shorten its life doing that.

source? I thought lithium battery had no memory.
It's not a memory issue, running a lithium battery flat (deep discharging) has a physical effect on it where it will lose it's ability to recharge to as high a level as the previous charge. Each time this happens the battery loses more of it's ability to reach an effective voltage.
Don't take my word for it, do your own research, there's plenty of information out there it internet land.

The dev for Dr.battery's has a thread that states that leaving your Touchpad on the touchstone for long periods of time should not impact the battery. Due to it switching to powering the unit after its charged. Though he is doing some testing on that. Also his app should be updated soon for the Touchpad (available through preware). I am still going to contact HP to discuss this as well. I would hate to damage a non replaceable battery. Will update if I have any new info.

I have done my own research. That's why i don't think this is accurate.
If you have some proof please share.
Besides common aging, a Li-ion battery can also fail because of undercharge. This occurs if a Li-ion pack is stored in a discharged condition. Self-discharge gradually lowers the voltage of the already discharged battery and the protection circuit cuts off between 2.20 and 2.90V/cell.

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Basically through normal use you can probably expect around 250-300 full charge cycles (partial charges only count as partial and add up with other partial charges to be a full cycle) in an average battery pack before it has degraded to 80% of it's original capacity. I don't see anything that point to full discharges being damaging. However storing it for longer periods of time fully discharged can affect life.
ambivalent-one I think the figure of 250-300 charge cycles you've pulled from that page refer to deep discharge cycle tests done by them, personally I'd be very unhappy with that kind of lifespan in a battery in regular usage. The same page you've posted http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries shows a chart of charge cycles versus depth of discharge.
Table 2: Cycle life and depth of discharge
A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.
Charges - Depth of Discharge
500 - 100% DoD
1500 - 50% DoD
2500 - 25% DoD
4700 - 10% DoD

As you can see a L-ion battery can be made to last nearly ten times longer by keeping the charge level up near max.
Quote from http://www.batterieswholesale.com/damaging_batteries.htm
The Li-Ion cell should never be allowed to drop below about 2.4V, or an internal chemical reaction will occur where one of the battery electrodes can oxidize (corrode) through a process which can not be reversed by recharging. If this occurs, battery capacity will be lost (and the cell may be completely destroyed)

Your research must've been incredibly basic in that case. The 2nd result I get when Googling "lithium batteries" gives me the wikipedia page which has a small amount of into on it:

Look at the "Safety requirements" section for a start.
Also Google "lithium batteries discharge" returns some useful links.
Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.
So the way to have 1500 cycles is to only use 70% of battery at best. Because going under 10% is not exactly good for the battery either. I don't want to have an even worse battery life, so I think I'll pass, thanks though!

Dont let them fool you, you dont need this app. The charging controller of your phone actually already has its safety margin built in. Same on the low end. This means you can not charge your phone to its physical maximum anyway, it will show 100% whipe the physical charge in fact is ~95% and will shutdown showing 0% while physically there is still about 10% of power left. So your battery is safe from this kind of damage anyway.
If you want to extend your batterys lifetime for real, try to charge it as often as you can, keep the charge as high as possible. Flat charging is the magic word. This is what your charging controller does when your phone is connected to ps for longer when it shows 100%, it in fact lets it deplate 2% without showing and then charges it back, thats called trickle charging and is the best treatment practice for our bateries.

Samdung pretty much confirmed they do this (or better) in the S8 and later (and possibly the S7). But has any other company confirmed they have battery longevity tactics built in?
Personally I use AccuBattery since I've had it for a long time as a charge alarm/monitoring tool. I use a 1 amp charger instead of the 3 amp charger that comes with it and charge my phone at low amps and voltage which prevents the battery from heating up. So low charge, low heat. I don't want a degraded battery in a year because I don't know when I'm replacing this thing.

AccuBattery is no good for giving an accurate estimate of the actual capacity when you're charging at low %s. For first 50% it'll calculate something like 3500mAH+, for the last 50% it'll estimate 2000 or lower. If I had to give you a rough estimate of what I actually think it's at, it's roughly 2900-3000mAH. When I first got it, I estimate it was around 3100-3200 a year ago. I HATE that phones no longer have replaceable batteries. That's half the reason I wanted an LG V20, I could just murder the battery and just pop in a new one every year. Sadly the V30 is sealed, following the BS trend of planned obsolescence. Thanks Apple.
Oh and I almost forgot, I typically charge my phone from 20% to 50% after it drops 30%. Then sometimes once more if I use it some more. On average I charge about 50% worth a day without going over 50%. Even with such light battery usage, keeping the battery 30C or lower 99% of time, and keeping the voltage below 4.1 again 99%, it's still degraded at least roughly 200mAH in a year. Rarely when I know I'll need longer battery life I charge it to 80%. It's a cheap quality battery. ZTE cut corners. This was my first, and unless I have no other reasonable options, it'll likely be my last ZTE phone.

my old sony phone form 2011 still works nicely, as it had Quality battery (over 2000 cycles already) yeah does not last long 2/3 but still. useable.
And i agree, replaceable batteries is must have function, My old S3 and S4 worked for "ever" because of that, every year new battery and another year of usage! (s3 still going strong since 2012 !!! )

You can do better than the app by setting a lower maximum voltage on the Axon 7 instead. I posted about the discovery awhile back on that thread https://forum.xda-developers.com/showpost.php?p=74746734&postcount=1353

Essentially, yes, that's what I keep hearing whenever I dig for information. If any of the stats of AccuBattery are accurate at all then it also supports that going over 80% causes multiple times the degradation that charging up to just 80% would. These days I try not to go over 70% based on app estimates of degradation. These days I need more than the 50% I was previously charging to.
OK, first of all, we all know that the S6 has NEVER been known for being a battery life champion. BUT, here's the problem .....
Battery reports relatively consistent decline in charge over time, until it gets down to 1%. At that point, the device still has sufficient charge to run for about one hour with the display on and set at full brightness.
Same on Stock Nougat, L.O.S 14 and L.O.S. 16. Same after full factory re-sets on all three. Same on pull and re-connect battery, which is a factory-new Samsung replacement for the original (not the 7 edge mod)
OBVIOUSLY, there is something not quite right about battery capacity reporting here.
Suggestions?

Ion Lithium batteries do not like to be completely discharged, to my knowledge ideally they should always be operated between 20% and 80% of their capacity.
Some laptop's do shut-down them selves when battery reaches 5% to safe guard the battery health.
So, yes, 1% reported by the battery does not actually include the "reserve" charge to prevent damages and, unless you really have to, do not use you phone with battery below 10% and charge it !
Under normal circumstances

Under normal circumstances, yes, definitely, keeping it between 30% and 80% is ideal, but when the goal is to accurately calibrate the battery / charging monitor circuitry, more accurate results are to be obtained by running the device to the point of battery exhaustion, at which point the reserve capacity designed into all lithium batteries still remains. But this is NOT something to think about doing on a daily basis. An S6 or S6 edge first run to the point of shutdown will actually re-boot but shut down just about immediately thereafter - iterations are not advised. You want it to have just enough left to get it to re-boot and stay running while charging, at which point you can monitor the recharge . Check out the data from Battery University or the support pages for Accu Battery for more details. Trying to use up the built-in safety margin is a fool's errand, and if you've ever seen a mishandled lithium cell turn a vivid red while the device in question melts around it, it should give you a healthy respect (if for some reason you did not have it in the first place) for not messing with or even attempting to mess with the reserve. The problem here is that the "1%" remaining on the charge meter (which is above, beyond, and independent of the untouchable reserve) actually appears to represent about 15% of the rated capacity of the battery, or in this case, over an hour of screen-on run time, and by never running that out, a current-flow-based app like Accu Battery will invariably under-report capacity going forward as a result. Such apps measure how much current is drawn to get from 'x' percent to 'y' percent being reported, but when the amount of current draw to get from 1% to zero is a range of around 300 mAh, for a battery nominally rated at 2,550 (for an S6) or 2,600 (for a S6 edge) as the total capacity, the problem of how accurate the "1%" figure is should be kind of self-evident. I am not willing to see how low a "0%" capacity report can be pushed down. Sanity has to rear its ugly little head at some point, after all.
Many alternative kernels, etc.. claim to address this problem, but I have yet to find one that actually does the job. It is rumored that Samsung service facilities can do a complete reset of the capacity reporting capability, but who knows? Maybe the luck of the draw gave me a dud battery from Samsung as the replacement. :crying:
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.
