Did HTC change the way devices operate when plugged in?
With the original evo 4g, it would run off the battery even when plugged in. Is that still the case with their newer devices (including the lte)?

I don't know the answer, but a fascinating question. Laptops don't run off the battery when charging (at least I don't think any ones I've ever owned do). So why should phones? They're basically little computers now anyway. I suppose we'll need a manual to know the answer, or an HTC rep.
While I agree with your assertion above, that was not the case with the original evo.
As is recall, this is demonstrated by using battery monitor widget or similar, with history enabled. The data would indicate that once the phone reached 100% charge, it would begin to discharge until about 90%. At this point it would start charging up again (until 100%) and the cycle would repeat.
If the phone is running off the charger while plugged in, the battery level should remain at 100% the entire time. Sure there were kernels available that would change the charge rate or thresholds. Anyone with an evo 3d care to chime in?

That seems rather silly - what if you grab the phone off the charger when it is just down to that 90% marker? It will show up as 100% I presume, and then drop rapidly down to 90%? Hmmm... No wonder those SBC kernels are so useful!
It's the same reason most new laptops give you a battery health option that only charges to 80% if you keep a battery at full charge for an extended period of time the cells will overheat and eventually lose some of their charging ability kinda like when you use a float charge on a lawnmower battery it's on a constant charge and discharge to keep the battery healthy same rule applies here.
Whatever they do/did, I hope it's well thought out, considering the battery is not removable. Once the cells degrade,...phone is shot. A bit disappointing. I'm not here trying to fight about nonremovable battery and how long it will last, and ability yo swap out batteries. But the idea that battery degradation (which is inevitable) = shot phone DOES give me pause and concern.

Even after a year, there is noticeable diminished battery capacity. I've had the seidio 3500 in my original evo since about feb or march of last year. Fast forward to same time this year. I'd say it easily lost 20-25% capacity. With my typical usage, I could go for up to 4 days without having to recharge (yes, light user). Now, it's 2-2.5 days. I was bothered by it enough that I did an rma. Seidio said that's normal wear and tear. Fortunately, the credit card I used had an extended warranty feature too, so that's what covered it.
There will likely be a tear apart video/howto posted eventually on the evo lte. Although the battery may not be typical user replaceable, i'm confident it is possible to open the device with minimal damage.
I'm sure there will be a way to switch batteried, you'll just have to go to a phone tech probably. I'm not worried anyways, I'm still using my stock evo battery and it's still going strong

I'm sure you can fork over some cash and get the battery replaced. I wouldn't lose any sleep over this. iPhones have survived with non-removable batteries for many years (although I always used that as a "con" in my comparisons between Apple and Google's respective phones).
My Evo 3D will discharge to 95% then back to 100% and repeat. It is done to keep the battery in good health longer.

Bump since no one has given input after "release". Very interested if we will still need to do that "turn it off, charge, unplug, charge, repeat" thing.

i would guess the phone uses the usb power source and not the battery because a few days ago my battery was low and i plugged it into my car charger and continued to use the phone,A few moments later i got notified that the phone was useing power faster than the charger could supply it

This is true, But iPhone users have no choice. So they get used to it.
Android, at least for now, has choices regarding removeable batteries.
IPhone users also have a 3 1/2"? size screen, which they got used to.
I'd Never purchase an Android device with that size screen, even if it was available. I highly doubt they'd sell many of them with that size screen.
Reminds me of when I thought my HTC Touch Diamond's screen was so large, compared to my previous clamshell devices prior to that lol!
It was such a nice screen for its time, just like the iPhone was a nice screen for its time, but that time has long passed, except for iPhone users :-(
Anyone else experience really crap battery life. I have had this phone barely over a year and now it is down to about 3 to 4 hours of of texting and snap chat and then it is nearly dead. Today it used 30% in an hour and a half. i send 5 texts and 3 snap chats. I am starting to believe the flag ship phones are BS. I do not think I will invest in high end after this. My iPhone SE work phone granted it is a small budget POS and an iPhone but I i leave that that thing off the charger for days at a time and even with all day usage it does not get below 50%.
My next phone all I need is a good camera and ram to load things quicker and a monster battery. Phones like moto G and E and some of the lower end LG and Samsung phones are starting to look more appealing.
I would switch out the battery for a larger but I do not want to change phone backs. The phone is already a giant brink in my pocket, do they make a GOOD higher mah battery that fits the same cover?
My battery life sucks also. I've had the phone about 2 years now and I'm lucky if I can get 5 hours of standby power. and yes I use greenify and Doze. if I use the phone for anything like calls or pictures or surfing, forget it, I'm down to two hours time. Luckilly I keep it plugged in whenever possible.
Ditto. I like this phone ok, but the battery life is terrible. I don't even use it that much during the day, but it won't even make it an entire day without charging. And no root sucks.
If you turn off all the crap that auto-runs, including location when not needed, things will improve greatly. But, you need root to do these things.
yeah, this thing has totally crappy battery life. I am an uber and amazon flex driver, so I use my phone all day, every day. The only reason it doesn't die constantly is I have a charging cable hooked up for it next to my car mount and it gets plugged in every time it is on my dash. Even still, I have to plug it in over night or it will be dead as hell in the morning. I actually have 2 extra batteries for it, but can't use them much because I have no way to charge them outside of the phone, so they are always low. I did just order a chrger base for it that charges my phone and an extra battery at the same time, so hopefully that will help, but this phone is really useless without extra batteries. As a side note, my girl has a cheap cricket lg, also, and hers just barely makes it through the day as well. it hits the low battery warning on her every single night and she only uses it after work. so she gets like 9 hours standby and 2-3 hours use... I kinda think lg just sucks at picking a battery size for their phones or batteries just need a new leap forward...

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Wow I did not know any of this. I will be following this thanks for sharing.
how long is the battery lasting if you are only going down to 50 and up to 90?
Gees! Below 50% really. I would tend to agree somewhat. I never let my phone fall below 20% and usually charge until 97% more or less. But 90-50. I don't want to be walking around with a battery back. I need my phone to last all day and 40% of the battery just won't cut it.
Xuck that !! I have a 3000mah battery for a reason if it goes then it goes ill most likely have another phone by then.Not gonna sit here to nickel and dime my usage that's not why I got this phone .
GM makes the Li batteries last in the volt and bolt 10 years by not letting the car drain the batteries more than 2/3rds down, leaving the batteries at 1/3rd charge. Tesla does it too.

Nah, I don't own my phones for more than a year so this doesn't apply to me. I'd rather keep using it from 100-1 just like I've been doing for years. I wouldn't be able to stand only getting an hour of use and charging it 3 times a day.
This battery information applies to all devices that use this type of battery be they Samsung or other brands. Its not just the Note 8. It applies equally to your Oral-B tooth brush! :laugh:
Ryland
this is a good habit to charge often at 50%. i usually let the battery run down to like 20% or less then charge. then when i have to go somewhere and i cant play with my phone anymore cus i worry i going to run down the battery.
Question are the "300-2500" charge cycles just as it says? I mean if I put it on the charger in the car for a 10 minute drive is that a cycle along with an overnight charge? If it is we should really only be putting it on the charger from the 50-90% with a guaranteed fast charge time of at least 30+mins to get the maximum charge cycles for the lifespan?

This was a really well written down to earth article about battery care. Thank you. I still have friends, family, and coworkers that insist on running their batteries to 0%. I can't convince them otherwise. Although my batteries degrade, it's never been anything easy shattering. Just notice an hour or two shaved of over a couple years life. As the article states, there is no way around this and I won't be a slave to my battery. In that note, I top off when I can.
My battery on my old phone tended to get to around the 40% at the end fo the work day, then I'd plug it in usually around the 20-30% and it still lasted 2+ years 'til I got a new battery. Now it's about 50% at the end of the day. But with Fast Charge, what do they expect people to do, plug it in for an hour, then unplug it, then go to sleep, wake up with 60% battery, go to work and then charge it for an hour when you get there?

Too black and white.
It is possible to offer some water resistance to a mobile that has a removable battery, S5 for eg.
In general such water resistance is small and is often abused by the owner causing problems. Hardly any owner reads the instruction manual that outlines what ones device can and cannot do, what the IP rating means in REAL terms etc
"Forced obsolescence" mmmmm, a battery can be changed in the Note 8. I understand your point though.
Ryland
this has been around for years. Doesn't make it very convenient to use nothing below 50%! I'd need at least an 8000 mh battery!! Therefore Samsung IS using too small a batteries in its top of the range device!

Totaly agree......
We then have to ask 'ourselves' WHY! Who forced Mobile brands to make anorexic devices? WE DID. We wanted thin small large wide slim ...........we got it and now pay the price.
I personally don't care if the device is thicker with a larger battery, for me its not a problem. For so many size was a major issue so the manufacture's listened and came up with these ultra thin mobiles that are vulnerable to dropping and breaking etc. off topic.
I find it totally bizarre that we spend mega bucks on such devices only to find we are educated to use them on software that reduces said mobile to the performance of a phone costing 100€! I may add many posters where disappointed when the Note 8 didn't have a 4k screen! Can you imagine the battery issues then?
Now we read this Samsung article and find we would need to charge our mobile several times a day as well as run it on a vastly reduced software programme. In reality that article is saying the battery is only operating efficiently at 40% of its total capacity before we start to degrade its life! Its all so absurd. What are we doing here folks?
Only one answer to this, either drop the performance OR vastly improve battery technology and fast.
Ryland
I'm not sure how usefull this is for the new samsung phones though, as the release of the S8 Samsung improved the battery.
Samsung Mobile R&D VP Bookeun Oh told me, "I focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. For example, after approximately six months of normal usage, the battery in the S8 will outperform previous batteries. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity."

PC mag S8 review
I am sorry but i will use my phone all day and charge overnight. If you can't use past 50% what is the point???? My pixel xl i have had since day 1 and use all day everyday and charge overnight and noticed no real decrease in battery life except a little change with oreo!
Outdated info and not necessary.
0% on your device is still considerably above what is considered the bottom line cell voltage before excessive discharge detrimental affects capacity.
A lot of engineering has gone into these devices to squeeze every possible mAh out of the packs, have a decent life expectancy AND operate safely. There is no need to strive for certain numbers and forcibly change your usage habits. There may or may not be a demonstrably better result long term but honestly is it worth worrying about?
And for removable packs...
Forget it. That's a thing of the past.
If devices had battery life like the Skyrocket, sure I see the NEED for a swappable pack.
But not now.
Having a sealed device makes it feel solid and keeps intrusion protection intact.
Holding an older device in hand, it seems almost laughable today. It creaks and groans and feels super cheap in comparison like some dollar store toy!
Hi,
I love the speed this charges … up 12% in the time it took me to make a coffee but that got me thinking...
Is it safe for the longevity of the battery to use whenever its time to charge or your phone or should you really only be using it in them times you really need a fast charge and keep a puny 2a 5/9v for them longer periods, such as overnight
EDIT: and now that's about 40% and the charger is pretty toasty, battery warm to touch also
Let be any Lithium batteries, slow is generally safe and will guarantee longevity of battery. 40W is a Huawei's throw in the face answer to OnePlus, that's it. So I would suggest 5V-2A to be good. 500mA laptop output is safest in my opinion, slow yet tension free.

No, of course it's not safe to use it often. I'd limit it to once a year, personally.

If it was risky, Huawei wouldn't offer it, particularly after the Note 8 disaster.

Well Dave, I said for its longevity... not is is at risk of catching fire like the Note 7.... and that was do to with their faulty batteries and not their chargers
yeah it would degrade the battery faster than a slow charger if you use it daily and keep the phone for 2 years you might notice it. I'd suggest a slow wireless charger for overnight charging (it also causes more heat that plugging it to a cable doing 5V and 0.5-1A but it is pretty convenient to just put it in the pad right before going to sleep and in the morning just pick it up with one hand) and 40W for fast boost when you need them
I think they've done their homeworks and it's safe to use for longevity. Looking at numbers in AccuBattrry, it charges as fast as 7000mah at first but once it gets around 90%, it slows down to like 500-1000mah (note I didn't check this over and over thoughrouly) to help battery longetivity.
That said, I don't think anybody here can often anything more than a personal opinion. Unless we can find a technical document from Huawei regarding this, I'd say nobody knows and we'll see in a year or two...
That said, the phone battery is supposed to be 4200mah but so far AccuBattery always reports 4000mah after each charge (it used to be accurate on my old s8).
Wonder if I'm the only one? Or is Huawei 100% charge actually stopping at 4000mah and saving the last 200mah for better longevity so it takes more months or years before it feels like the battery lasts less time?
I'm sure they know what they are doing. If you look into how batteries work (any batteries, the same rules apply to your car battery) they can be fast charged without harming them up to a certain percentage. After that, trying to cram the juice in reduces longevity. This is all well understood at this point, and they wouldn't ship the phones with the 40W charger if it meant a chance of evidence coming out that this harmed the capacity or longevity (number of charge cycles) anytime soon. At max charging speed the phone barely gets warm, which was always a tell-tale sign of overcharging.
On a side note, the 2013 Nexus 7 (which had a terribly underpowered SOC/battery for the screen) was so terrible at drinking the battery that custom firmwares gave you the option to only charge the battery to 95%. Note that this has nothing to do with charging rate, or any of that - simply a cap on that last 5%. The result of this was an estimated SEVEN TIMES bigger amount of charge cycles for the battery. In other words, even when you trickle charge a battery for that last few precious percent, you are doing damage - that is inherent in the design of all batteries.
The efficiency of this Kirin 980 is *ridiculous*. They said that the battery would last 2 full days. They didn't mean it *could* last 2 full days, they meant it *will* last 2 full days - even under fairly heavy usage. It is almost impossible to believe how advanced power consumption efficiency has become, especially given that this is an 8 core (on the main 'CPU') fab capable of performing 5 TRILLION floating point operations per second. I don't think people realize the scope of that number - it makes an S9 looks like an 8 bit Nintendo by comparison. Like the A12 Bionic, it is nearly 10 times the raw processing power of the iPhone X, which was already handily kicking in the ribs of any other phone by orders of magnitude.

If you do some reading you will see that charging over 80% and draining under 20% will significantly shorten the lifespan of your battery. This is important for those of us that have devices not sold in our country so getting replacement batteries would be very difficult and expensive. I have phones that are more than 9 years old and still going fine if charged like this.

On the contrary. The most recent phones attempt to limit the time that they spend at 100% exactly because it's so bad for battery longevity. Having options like the OP's approach just gives users more flexibility, should they want more control than, in this case, Google's adaptive/AI approach.
And it's not 'wasting' 40% of the battery. Keeping between 80% and 20% just optimizes battery service life during those days you only actually only need 60% of it's possible capacity. When working from home that's often the case for me. I actually tend to use ~30% of the battery in a day. Better to charge it up daily to about 70% than all the way to 100% and let it go down to 10% over 3 days. If it's easy to do, why not?
Not quite the same, but EV design also has their batteries normally operating in the middle range so as not to compromise their service life...
Definitely not myth. The only myth is that lithium cells exhibit a memory effect and need to be deep discharged and fully recharged periodically to maintain their capacity. It's actually bad for them to do this! The only reason to do this would be in an attempt to recalibrate the software for the battery level gauge (at the cost of a little damage to the battery each time you do that).

Most folk don't notice reduction in battery capacity until it becomes severe. For example, a friend claimed it wasn't a problem charging his iPhone to 100% ritually. When he checked the OS, it said his battery capacity was 80% of what it was when new. He said he hadn't noticed it affect how long the phone lasted.
If your usage is such that you can predict how much capacity you need, you can choose to charge to 100% only those times you will actually need that capacity. Other times you can look after the battery so it's able to actually give near on 100% for longer, those times it's important to you.
Others who keep their phones a short time or are comfortable with the cost & inconvenience of a battery replacement, or simply don't care, don't have to worry....

This all maybe good if you are planning on keeping your device for a few years.
Most people buy a new device every other year. If not once a year.
... and if you really want to knacker the battery, heat it up too!
Worst case scenario - using a sat nav app on your phone in the car on a hot day with the phone plugged into a car adaptor. It's going to be sitting there at elevated temperatures, possibly with the sun shining on it, whilst being kept at 100% battery....
I'm only a customer (and have no other affiliation) and like to tinker, so I got one of these for use in the car to limit temperature when charging and limit max charge. Not cheap, but ok compared with the cost of the phone https://chargie.org/
I'm sorry, but at the snails pace this phone charges I'd be very surprised if charging it to 100% every night will make any noticeable difference in the long run. I had a Xiaomi Mi10 Ultra with 120W fast charger. That phone used to charge from 0% to full in like 20 minutes. Now that's one way to quickly kill your battery.
The Pixel uses your alarm to adaptively charge the battery so it should never overcharge it anyway. I'd much rather us all of my battery than use it only between 20 and 80% just for it to last a little longer.
The files are overwritten on reboot so I created a Tasker task to write the values on reboot each time.

On what basis? All the research and tests are based on charge level not charge rate. Fast charging potentially just makes it worse...
But at the end of the day it's your phone. You'll charge it in whatever way works for you.
I feel like this post sort of misses the point. It clearly is aimed at those intending to keep their phones >1yr, it is stated explicitly.
I'm not rooted right now, so I've been using the AccuBattery app. One of the things it does it gives a notification every few minutes when the battery is at 80% or above so that you can physically unplug the phone from the charger. Obviously having this done automatically would be better, but I've been surprised at how well the notifications have worked in my case. Plus, I can always leave the phone plugged in if I know I need a full battery for some reason (ie a long day away from any charging source).

I was wondering if changing the file permissions after writing to them to read-only would make the changes stick, but I am sure the OS could still overwrite them...??
I wonder if there's a similar variable to tweak at what temperature the phone considers the battery is too hot and stops charging?

If you edit these files and put you own values in then your phone will start charging when it drops below 75% and stop when it gets to 80%. (put your own values in, etc.)
I have only tested it briefly but it seems to work for AC and USB charging for me so far. No other apps or tweaks needed.

Did a bit of testing and it works fine. A few things I noticed:
1. Doesn't survive reboot. Now that I've set up MiX with pinned folders, I can make the change in seconds. Need to sit down and read through the acc documentation because AccA doesn't work. Would love to have an automatic solution. Miss my old Battery Charge Limit.
2. charge_start doesn't seem to matter. After all, if charge_start is set to 75 and the phone is at 70%, it shouldn't charge. But it does. I've kept mine at 0.
3. Point #2 is kinda beside the point, though, because charge_stop will stop at the set value and stay there. No noticeable increase in temperature from what I can see. Definitely less than when charging.
4. Still shows as charging rapidly when it hits the level. Is it rapidly cycling charging on and off? Or in a kind of micro-current state? Or this may be a true battery idle situation where all power is drawn from the adapter. Ampere and AccA just show "not charging".
Edit: With a bit of use today, it does seem to act like a normal min/max charge deal, so I set it at 75 start/76 stop. Not sure what was happening at first...maybe something to do with the adaptive charging since I still have that on. Either, way, no complaints. With my use case working from home, I have it plugged in most of the day and it'll only take me about a minute to change charge_stop to 100 when I'm planning to go out all day somewhere away from chargers. Not ideal, but still a big improvement. Changes my rating of the thing from maybe 3.5 stars to 4.5.
