I charge my phone up to 100 percent and even on standby it goes to like 90 percent in about 3 hours and to about 80 in about 5 hours...is this normal....I don't believe this is a normal standby time for any phone...
also does the phone get extremely hot when using navigation without charging???? I get about 40 minutes of navigation and the battery is at 55 to 60 percent...is this normal for everyone???
I called HTC they said the phone should NEVER GET WARM OR HOT and getting that much battery life for navigation is just crazy!!!!...they said the only time the phone will get a little warm is when charging the phone, but never hot...just slightly warm.
also it is the phone itself that is getting hot not the battery.
defective unit???

Rumor has it that the update to software version 1.36.531.6 addressed overheating issues. Not sure of the effect as I updated my phone out of the box. I've had my phone for 5 days now and have not had any overheating issues at all. I have not used the nav for any extended time yet, but keep in mind that it used the modem, gps and display so your batter will drain a lot quicker.

The other day my phone got hot - very hot - during a 1/2 hour conversation using a VoIp app (Viber). It reached 114.4 Fareinheit degree. At that point I was on Stock 1.36.531.6 (NOT .5 though)
Testing it again using the same VoIP app with the same length conversation on QuikSense 1.5.1. Temperature stayed at +/- 100 F
114 is a normal temp, phones dont have cooling fans like a pc.

'Course I known that phone doesn't have a built-in cooling fan
Or maybe I should email HTC and suggested them to built-in an AC unit then ..
Would you kindly post some kind of a proof that 114F is a "normal" temp
Please enlighten me a bit since my phone normally showed temperature between 70's up to under 100's max - and I can proof that with screenshot
* 1st pic at 22nd row:
Baterry discharged at the rate of -1023mA = 82.2F

Baterry charging at the rate of +862mA = 78.4F
* 7th pic - 25th row:
Baterry discharged at the rate of -1013mA = 80.9F

Thanks for the suggestion.
I did tried to narrowed down an individual app that may caused the high temp without succeed but the problem did not existed when using Xboarder's QuikSense 1.5.1 in the exact same situation/setting and I'm happy with that.
Just wanna share some experiences with others who may have the same issues though

seems like I'm one of the few...I will be exchanging the phone...you are right...I did pay the entire price of the phone...no contract...so yea...will be exchanging it.
Mine overheats from time to time... I have not noticed a pattern.
The phone is a battery whore.
I work in front of a pc all day so it's manageble. With a monster screen and processing power, I expected it to suck.
I did notice a decline in overheating since the last update.

Battery and charging issues
I have an Amaze from Telus. The phone charged up fine and worked well with decent battery life. I am in the U.S. and now when I have fully charged the phone while its off and then turn it on the bootscreen loads but then the phone dies. Could it be the Supplied Charger or the USB Cable is not giving it enough of a charge? When I swapped out the included HTC battery with an Anker battery it powers up and works fine. Does anybody have any ideas? I have read that some of the Micro USB cables were problematic and didn't allow power to flow to the phone. I have also heard that the HTC power adapter also has had some problems as well.
It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Google Pixel 3a before depleting the battery.
Then, drop a comment if you have anything to add!

You got 8 hours on the regular one? I used to have the 3A XL but then gifted it to someone and an now using an galaxy S9. Really miss having a pixel though so am thinking about picking up the regular 3A and was wondering how the battery would differ

Yes it's the 3a. I think i could get more SOT without gaming.
From full charge to zero, I could get about 10hrs of screentime consecutively browsing, but that's not how I use my phone. In 48hrs of 'normal usage' I get about 5hrs of screentime.
I do about 3-6 hours of BT audio streaming daily which is why there is a larger than normal screen off usage. Still nice average SOT. I have so many sessions because I try to keep my battery between 50 and 80% for longevity.
I get 8 good hours.
What does Android 10 Battery say? Screen usage since full charge? Also Full charge lasts about???
Mine says 1 day 11 hours of typical usage. I always charge at night so it has rarely if ever run out.

Worse, on the best day you can get 6.5-7 hours on the regular. On the XL it's possible to get 9-10
I got my pixel 3a a couple weeks ago and struggling the last week or so getting more than 3.5 or 4 hrs SOT. I did use GPS for a 2 hour drive home today but it's 3p and I'm down to 10%. Idunno what's going on.

the app usage of 66% is a clue. maybe you got some crazy app eating up battery. if you have bluetooth and/or wifi scanning on continuously that can drain a bit. gsam can be setup to show which app is using most by doing the adb command. just select apps for the details if you have not already.

Here we are after factory reset and flashing the latest OTA from
https://developers.google.com/android/images
Still can't hit 4 hrs SOT. Not once. I really don't know what to do at this point. Incredibly frustrating with everyone else on this thread having MUCH better results.
GSAM is showing some pretty beefy wakelocks on that "RemoteSoundTriggerDetection" and "*alarm*", ActivityManager-Sleep, etc.
I bought it from Best Buy. Should I go up there and see if they'll replace (highly doubt it) ? Maybe flash a custom kernel?
screen on time is a function of what a person normally does with a phone. one way to get high screen on time is you could set display intensity to 25% and timeout to 30 min. if you need that number to be higher. just let the screen be on as much as possible. when you first got it did you fully charge it then fully discharge it then fully charge again? screen on time is about the last metric i ever think about. i don't understand at all why it's so important. i'd be willing to bet some users set intensity to 20% and time out to 30 min or always on and do very little else then they get s.o.t. of 8-9 hrs or higher and think it's great when it's a joke. that's the way i look at it anyway.

Not sure if you're replying to me but I'll answer anyway. Yes I fully charged it then fully discharged it then fully charged again when I first got it.
It's not the SOT that is so worrisome but the constant Android system and kernel drain on my device.
I'm getting worse battery life on my 6 week old 3a than my 2.5 yo OnePlus 5 which wasn't good to begin with. This device was lauded for having excellent battery life and I'm not seeing it.

It isn't that at all. I found using it for anything where the phone needs to utilize the GPU a lot, like gaming, drains battery substantially. "Light" workloads, like web browsing, using social media apps, streaming video, etc give you really good battery life. Once I start up a game, I see about 5-6 hrs compared to 9.5 hrs if I just stream YouTube, check the XDA app, email, Reddit, etc.
Hi,
So I've been using an app called Battery Charge Limit from the Play Store (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit) to limit my battery charging upto 80% using root access. This was to increase the longevity of the battery.
Worked fine on Oreo, but now for some reason it doesn't seem to stop the battery charging at 80% on Pie. I was wondering if anyone else has encountered this issue and has found a fix/workaround?
I know its probably better just to ask the app developers, but I was just wondering if anyone else is having this issue as I also have access to an S7 Edge on OneUI Pie and it doesn't seem to have any issues.
Thanks

I do not see any sense in such charging settings, the V30 with 100% notification is still charging for 30 minutes with low current and then only reaches a physical 100% battery which is to save the battery. As the program disconnects charging at 80% it will be physical about 70% = 2/3 for battery use. You probably don't discharge the battery less than 30% because you will "damage it". Then use 1/3 charging it 3 times at the same time as I do ... So think about whether after these 4 years you won't have a more dead battery than I, kids, I charge 15> 100%.
Yes, the answer is simple, charge up to 100% and disconnect immediately, just like LG limits charging to physical 95% so that the battery does not lose capacity.

Fair enough. I simply limit it to 80% as from what I understand the majority of battery wear happens between 80-100%, even if it is charging at a much lower voltage and current.
Even if the phone doesn't show the true values of physical charge, a physical 70% charge is enough to get me through the day and I don't worry too much about how much battery I drain so only put the phone back to charge when it's at ~5%. So only charge the phone once a day.
Even if it may/may not make a difference to longevity it's worth a shot. At best it'll improve the lifespan of the battery, at worst it'll do nothing with normal degradation.
Maybe in a year or so when 80% charge can't get me through the day I might drop the limit. For now it seems worth a try.

Just for your information, deep discharges are also not very good for Lion batteries. Discharging to 5% regularly is as bad, if not worse, than charging to 100%. The optimal is to always keep the battery level between 40%-80%.
I am not so sure if that will make any visible real world difference since most people don't tend to keep their phones for too long. And since that limits the effective battery capacity too much, I would suggest that you don't worry too much about charging/discharging too much.

To answer your original question, the same feature works as intended on a different app (AccuBattery) on my phone, stock unrooted open EU H93030b. So it looks like your problem is not the OS but the app.

Yeah I am aware that discharging to 5% can be just as bad for the battery. But even if I charged to 100% I would still use the phone till there was only 5% left. So I just thought might as well try to limit the charging and see if it makes a difference on the long run, since 80% gets me through a the day anyway.

Thanks for your help! I did try out Accubattery and yes it detects when the battery is at 80%. Just wish it could set limits with root access as well.
In any case, I seem to have found a solution now. There's a Magisk module called Advanced Charging Control (ACC). This seems to work well and limits charging to 80%. It also has a companion app that you can use to set your own preferences and limits.
I've linked the relevant thread below, might be useful to others.

Your doing more worse then good letting the phone go to 5%. That app will not do ANYTHING for you.
Sent from my LG-H932 using XDA Labs
I find ACC works well at stopping the chargeing at a certain % level.
Hoiwever then while still connected to usb it draws power from the battery - not good.
Battery charge Limit on Oreo stoped charging and used then power from usbb onwards while still connected.
I wonder how ACC stops the charging on Pie, i.e. with what control file. Has anyone got an idea?
I foudn out that the switch is /sys/devices/platform/lge-unified-nodes/charging_enabled. This starts/stops the chargi8ng.
Unfortunately, on Pie, when this is set to disabled from then on power ist not drawn from the charger but from the battery.
Is there any other switch / wax to prevent this?
Ich want charging to be stopped and from then on power to be taken from the charger while connected to it.
Here are the paths to the CTRL files that I've found to work with the two ROMs that I've used recently:
Havoc-OS wired and wireless: /sys/devices/platform/lge-unified-nodes/charging_enable (no 'd' on the end, unlike what bladecgn gave)
Lineage OS wired: /sys/class/power_supply/battery/charging_enabled
Lineage OS wireless: /sys/class/power_supply/dc-wireless/charging_enabled
One quirk that I've noticed is that, on wireless, the app ignores the "Recharge below" setting and starts recharging as soon as the percentage drops just 1% below the max (ex. if the max is 80% and the charge drops to 79%, it'll immediately recharge back to 80%, even if "Recharge below" is set at 76%).
For the record, the ROM that I'm using is LineageOS 17.1, so the app definitely still works on Android 10.

Stock Pie doesn't have the /sys/class/power_supply/battery/charging_enabled file, but it does have /sys/class/power_supply/battery/battery_charging_enabled. Would that work?

I don't know. You'll just have to try. It's a process of trial and error to find which path works with which ROMs.
While using the Tab S7+ for almost two weeks now, I consistently get approx. 6 hours of battery life (that is with the screen on 60fps, half brightness and mostly using office applications like Teams, Outlook, etc.). With the huge battery included and some reviewers indicating they are getting up to 10 hours of use, I'm not sure if I have some issues.
What are your experiences with respect to battery life?
My screen on time is very good. Can easily get 10 hours of SOT for light browsing etc. A bit of video here and there.

Thanks! That doesn't sound too good for me
I just have my tab s7 plus. And I get 6 hours and 20 minutes out of my battery with the screen set to 120 hz. You know when your screen is set to 60 hz when you go to settings - display - motion smoothnes is set to standard. I am right now testing how long my battery last when my screen is set to 60 hz. If you want to know which apps are draining the most battery life. Go to settings - device care - battery battery usage. For its Google chrome
Just tested it and I can do 8 hours and 50 minutes on one battery charge while the screen is set on 60 hz. It's not as good as the reviews say on YouTube. But largely better than my very old samsung galaxy tab pro 12.2

It could be a manufactory flaw. But it is more likely that there are several apps on your tab that are draining your battery.
Mine is not a plus, so not sure if this is helpful. I get 10h from around 86% charge (I don't (dis)charge 0-100).
Mostly Netflix and video calls on wifi, some browsing, reading, and note taking.
This is with 60hz, and battery save feature which is supposed to limit max charge to 85% (Though that feature is questionable from what little testing I did.)
Check what apps are draining your battery. It's not necessarily a manufacturing flaw.
I am from India and i have the note pro 12.2 lte version which crazily enough i use as my primary phone. I have data enabled all the time with auto brightness mode on. I use the Galaxy Note 7 ported ROM for the P905. I use my note pro 12.2 to watch a lot of youtube videos, whatsapp chat, browse the web, checking and sending emails, reading word and pdf work documents, 30 to 45 mins of playing asphalt 8 and into the dead 2 and answering/making 4 to 5 voice calls a day. I get a solid 8 hours of SOT even now when i get the low battery alert at 15%. I got over 9 hours of SOT on Lineage 17.1 android Q but found the features too limiting compared to touchwiz and i missed the spen. And that is battery life on a 6 year old device. I do make sure to not charge it more than 90% and i .com not let the battery dip below 15% before i charge it. I guess i got lucky and got a tablet with a really good battery.
The tab s7 plus has almost the same size screen but has the major advantage of it being amoled versus the lcd screen on the note pro 12.2. Plus with the new power efficient cpu and a 10000 mah battery, i am surprised at the battery life most people are reporting. I guess being than thin comes at a price and there is less power generated mah for mah compared to the 8.8 mm thick P905.
Just got mine yesterday. The battery life is significantly better than that of my Tab S6. I'll see how it goes over the next few days.
Don't know exactly in SOT but working from home, I charge it once a day and am using it constantly from 9am till 11-12pm
I've change the changing procedure to slow. No fast charge, slowly changing and stop at 85(?) Prozent...It will be better for the battery lifetime

There's an in built option to stop charge at 85%. Though from my testing I don't think it's functional really.
I've checked the voltage on 100% with both on and off, and the values were the same.
Maybe someone who has it off could measure the voltage on 99-100 charge? Would be nice to comparte results.
We run CCleaner Pro 5.1.0 [for Android] set with max battery life and automatic cleaning mode. One of the useful functions is a 1-click Boost which puts to sleep/closes apps in batch mode. Appears to help with extending battery duration as we've run 5 days with everyday on/off use (messaging, browsers Dolphin, Puffin, Vivaldi, etc) between charging.
Also set maximum battery charge limit to 85 percent from Settings > Charging > slider button to On [85 percent]
I am a complete noob to the art of monitoring battery heallth & charging, not even sure if my question needs a new thread.
My S7+ has been in use for about 2 weeks. The first day, I charged to 100%, then enabled the 85% charge option and also installed Accubattery and set that to remind me to remove the charger at 80%. I have charged it only up to 80% ever since, on a slow charger.
Today, Accubattery Battery Health is showing Battery Health at 83% capacity. Does this mean the overall health has gone down by 17% in jus two weeks? Or do I need to learn a lot more about meassuring battery health, and if so, is there a dummy's guide anyone can point me to?
I bought it direct from Samsung, haven't made any ROM changes and am using the stock launcher. Love the tablet.

You can see the difference in AIDA64 Premium 1.74 [Android] (set to 100% > charge to full > set to 85% > reboot > charge to full)

Bro, thanks for the Aida64 tip to see the real battery capacity.
It says ( Reported by android ) 9800 mAh
and ( From Database ) 10090 mAh
Was wondering how to see if this samsung feature was acualy working.

What exactly am I supposed to be looking at there?
I have the same issue here. I even went as far as to ring up Amazon and get them to send me a second one as my battery must be faulty if its only getting <50% (6-7hrs) when its advertised to run for 14hrs.
Upon receiving my new one. I did various battery stress tests and found that the new one had an even worse battery than my old one.
(Bare in mind both of them are at factory settings).
I did this test for about a week apples to apples comparison, then eventually returned the new one as my old one (which is only like maybe 2 days older lol) performed better in every single benchmark as well as battery.
So I either got really unlucky receiving two units with bad battery or this is just the norm?
EDIT:
Upon doing a quick google search; it seems like this is true across the board.
https://uk.pcmag.com/tablets/128966/samsung-galaxy-tab-s7
5hrs and 28 mins according to google and this article
Either way, i've noticed if I play a video, it roughly loses 10% per hour; but when browsing i can easily lose 10-11% every 30 mins.

EDIT: You need to be rooted to do this, and you need to reapply the settings after reboot.
I have a Tasker action that does this automatically 5 minutes after rebooting.
If only there was a way to use that without root :-S
What would be the purpose for this.
I always charged to a 100% and never had issues on my devices.
I use the adaptive charging overnight and think that will help with battery life.

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.

If you would have read the correct information on this subject. You would know that this not true for today's battery technology.
This is nothing but a myth.
You will have a better chance looking for Bigfoot.
Why waste 40% of your battery use....

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).

Dumb question but what did you use to write values into those files? Did you use a text editor (with root access) or just termux or something? I tried with the built in MiX text editor but it seems to choke once I open up the file.

I used FX File Explorer (root option). Look for the #. SYSTEM (Root).
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?

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.
