Hi. I have my s2 with 2000 mAh Samsung battery, and on official firmware, and the battery is discharging very fast: 62% in 6h and 23 minutes on normal use. On F1 GalaxyNexus rom i have about 70% after 8 hours of normal use. There is a sollution to fix this huge drain?
Checking it simply, it can be guessed that your phone isnt going into deep sleep at all. Install betterbatterystats found free in xda and see whats causing the wake lock.

Your screenshots give no useful information to diagnose your alleged problem.
There's no such thing as "normal use".
Hi!
Have you installed any applications? It might be one of theese that holds a wake lock which prevents the phone from going down in "sleep mode".
Regards!

A bit of basic arithmetic tells me you've had a bit over 2 hrs of screen on time (that's a rough calculation), and you've used a bit more than a 3rd of battery capacity, so that indicates (again roughly) you'd expect to get ~6 hrs of screen on time.
What's the problem
Nothing wrong here if you didn't use a charger than 6 hours with 60% left means 12 hours easy.
I agree with the guy in the above post, Facebook potentially is the main culprit. Give it about 3 battery cycles? What kernel are you using?
Facebook is fine, he is using it that much, so are the calls. heck if I get that kinda battery while mostly idle I'll be happy.

For me this is normal or probably we have some issues before...LOL...
Right now, I use F1 GalaxyNexus ROM...I can describe it for one word "AWESOME"!
Get better battery stats from xda and cpu spy from play store. Bbs will see if you have any rogue app that's draining battery and cpu spy will see if your phone is deep sleeping

Hi everybody, i have a question :
I just got the marshmallow update for my note 5 and there's something I don't understand which is the battery usge .
In lollipop the battery usage screen used to show exactly the amount of power that each app used ,ex. Clash of clans used to take exactly 1% every 5 minutes .
So after updating to marshmallows it doesn't show that instead It shows a percentage of the whole power not the exact amount of power for example in the screenshot it says the screen has used 62% of the whole power.
So how do i calculate that to get the exact amount of power (in % not in mAh )?
sorry if my english is bad
So compared to lollipop are you getting better battery life on marshmallow? How does it compare to lollipop. Better battery life overall

I have been using the Samsung Galaxy A10 for 10 months now. Currently I'm facing battery issue (Discharging at irregular rates) and heating issues (On the screen - top - at the camera). I know this is a hardware problem. But , my battery has lost it's life over the age. My battery health is only 87% approx. 2987 MaH is left. But , the heating issue is going out of hand and it's crazy! It gets heated up for simple tasks like browsing on chrome watching a couple videos and so on on. The temperature is way too high average it's 35°C but it goes up to 45°C. It's like i can boil a egg on my phone. So I've been thinking of getting a new battery. So i taught why can't i use the Samsung Galaxy A50 battery if it fits. Have anyone tried this before or has anyone changed their A10 battery ? Please let me know.
What's the limit ? I mean everything has a limit and so does the circuit of a phone. Do you think it's safe using a 5000 Mah battery?
The question is will it fit?
Yeah , you are right. I've been searching for a higher capacity battery and i think A10S battery will fit. It's 4000 mah and where i live i can find it for less than $15. At the same time , i think i must act fast. My problem is kinda worsening. The phone gets hot for no reason at all! I'm afraid that it'll burst. Do you think that battery abuse maybe the reason? Draining the battery to 0% like almost everyday , using low quality charger , etc., please someone let me know ASAP I'm afraid!
So i regularly use AccuBattery app in my android device. It's a very useful one.
So i installed this on my new Poco X2. Those who've used it know that it can estimate your current battery capacity based on charge sessions and some other stuff.
And upon using it showed my Poco X2's estimated battery at around only 3800mah.
And a lot of users also are complaining about battery backup on flipkart.
Please check and post your device's estimated battery capacity via AccuBattery app.
Unfortunately, what Flipkart reviews say is actually right, this phone has serious SOT problems with 120 hz i only get 6.5 hours sot and 8 hours with 60hz and I don't even use it heavily just YouTube and small games with social media. This phone has very poor optimization. I know i shouldn't compare but if you look at realme 6 pro almost same specs but with smaller battery (4300) gives 1 hour more SOT even with heavy usage(both set to 60hz). This is absolutely disappointing, eagerly waiting for custom roms and custom kernels to make it as my daily driver. Will update you on the accubattery results

Thankyou, waiting for it.
Bafore this I was using standard China Rom with mine and battery was a mess. But I unlocked & flash MIUI.eu. I add-on "naptime" to help with Doze & using Universal GMS Doze magisk module. Managed to get almost 8hrs SOT with ads removed, bloatware removed & MSA removed. Maybe you should give it a try and see ?
Same
Battery is fine for me
Don't know how people here getting more than 3.8k mah estimated. Mine doesn't go above that. I'm pretty sure some units have battery problem as reported by few buyers on Flipkart. Some said battery is excellent while some said poor battery. I think poco x2 indian units are suffering more. Since after watching some tests on the redmi k30 Chinese variant by YouTubers they got significanly more SOT. I tweeted to them, no reply from their side yet ?
I got my K30 directly from China. No battery issues whatsoever.
I've been getting consistent SOT of 9.5 hrs on average with heavy use. SOT range for me has been 7 hrs (120Hz) - 11 hrs (60 Hz) on 4G LTE (you can check my post on SOT thread).
Being a heavy user, this battery life has literally blown me away and I absolutely love this phone simply for that. I can easily get thru a very heavy day with 30-40% battery left. I've been charging the phone twice every three days on average.
I'm on stock CN ROM (MIUI 11.0.13 Stable)
I easily get 8 hours + SOT with gaming. I play cod and pubg extensively.
Battery life update after using a month .
Mild gaming and social media usage.
Average sot is around 10hrs , battery lasts 30-50hrs depending on camera usage.
Unable to upload screen shot showing bad request.
Is AccuBattery reliably on first cycles? If many users have 3800 mah insted of 4500mah then something stinks here
My poco X2 shows 4398mah
I am on stock Indian rom miui 11.0.10
I did some quick research across the web and it looks like there are three types of d
1. Battery Drain issue devices, they have bad battery issues, battery capacity way below 4500 and widely varying with users. Screen off discharge is way off charts, like >5%/hr. SoTs varying around 5hrs or <5hrs
2. Inefficient battery devices. (Majority) They have battery capacity much below the specification, however less varying, always around 3800mAh. Battery doesn't drain that badly
I have this device, heavy usage like pubg clocks around 15-20%/hr, normal usage around 10%hr and screen off discharge rate at 0.5-0.9%/hr. Hardly discharges 2-3 percent through the night
3. Ok devices. These are the best sets. Battery capacity constantly goes above 4000mAh (still doesn't hit the required 4500 mark tho). No serious battery drain issues. (I don't know much about these devices because they don't look into the web coz they have no issues.

Usually i get around 9hrs 30 min sot on 60hz and around 8hrs on 120hz...( Without gaming ) after the update of miui 11.0.11 my phones battery backup gradually increased 1 hr on 120hz...+ I did some tweaks blocking system apps from running in the background
After using the phone for 8 months, I noticed that charging speeds have significantly reduced. At the beginning, the battery went from 0-100% in ~70-75 mins if I remember correctly (cross checked this with another review website).
But when I properly checked today (after a long time), it took 118 mins (2 hrs!) for the battery to go from 2-100%. I also plan to check this with the screen/phone off again.
The battery life is still great though, maybe slightly reduced compared to the beginning.

Maybe you charging cable could be the cause of this

Original charger used and the cable is in perfect condition.
Re-tested today with the phone switched off and it went from 4-100% in 70 mins! So all is good. Planning to test tomorrow again with the phone switched on.
Battery life is still stellar. 8.5 hrs of SOT for 26 hrs of usage on 120Hz; 70% WiFi and 30% LTE.
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.
