[Q] Battery life

Recently I've been experiencing absolutely terrible battery life. I lose about 1% every five minutes with the screen on - sometimes even faster - and find myself increasingly unable to last a full (work) day without having to plug in at least once. My current ROM/Kernel are LolliGPE (http://forum.xda-developers.com/showthread.php?t=2716306) and Elite kernel from when I switched from stock Kit Kat back in December. It's worth noting that I haven't gotten around to updating either since their installation. I can't remember how my battery life was back in December nor before Lollipop, but I'm almost certain it was better than it was now.
My questions are:
What ROM/Kernel do you recommend for the best battery life?
Are there any apps I should check for and uninstall that drain battery?
In general, how can I increase my battery life?
Thanks!

1. Rom/kernel combinations in regards to battery life, or pretty much anything, is a completely subjective experience. You're better off trying different combinations for yourself and seeing what works best for you.
2. To see if you have any rogue apps, better battery stats probably does the best job showing what is using your battery. If an app is an issue it'll show you exactly what's causing it.
3. Best way to improve battery life is to monitor your battery stats with a battery monitor and try to control your wakelocks as much as possible. You can Google search exactly what process is keeping your phone awake and fix your problems one by one.
In my opinion, the three biggest things that truly affect battery life is mobile signal connection, Internet connection strength, and Google services such as Google now. Trying a different firmware version could increase your battery life as well as trying different rom/firmware combinations.

I'm running Adrenaline 1.2 with quantum kernel 1.25 on stock 4.4.4 firmware. I'm getting the best battery life I've ever had with that combo. Then again, in bright light where the screen has to run at full brightness and with a less than stellar signal, it will still eat through power pretty quickly. It's just the nature of the beast.

Odd I am stock non-root and see the best battery I have ever had with Android

After experiencing the same problem as yours with the two mentioned kernels, i seek for solution and found one. backup all my contacts, sms, call log, bookmarks, apps then i did a clean install of fluent rom based on sprint port cos i love lollipop and the two devices are similar in many ways. Surprisingly i get 6hours of usage with just 20% gone and at least about 3 -4 h screen on at the same time. so my advice is to try clean install.

Here are Buckmarble's own recommended settings with the Elite Kernel:
Governor: ragingmolasses
Ioscehd: fiops
Read ahead: 1024
UV: -24 across the board
2265 max 300 min
I use Trickster Mod to set these. I have heard that the frequencies don't stick, but I haven't bothered to check because battery life (running Fluent ROM 2.0) is stellar. I put my M8 on extreme powersave yesterday when it was at 100% because I'm testing a different handset and when I returned to the M8 late yesterday evening it was "all the way" down to 95%.

Is Sony Lollipop stock still the best release for battery and features?

Is Lollipop still the best release for battery and features?

From my experience, for battery life, yes that firmware is still the best, but for features and overall stability, i think 6.0 is the best

what are the best features that makes 6 better? battery is 10% or 30% lower compared?

Granular permissions.

Recently i had Android 7N (dev. preview) installed on my Z3. So far it had the longest battery life..
Too bad most apps were force closing.. But the battery life it was really great.

Permissions yes, but you can't control internet (you still need NetGuard for that). Oh and security fixes.
Battery is more than 25% lower on may use case.

Battery Life Improvement

Anyone noticed a slight improvement in the battery life of their V-10 after the stock Nougat update?

Yes but not a whole lot of improvement I still run out of battery near half my day. I need a 6,000 mAh battery

I've noticed a difference. Usually within an 8hr shift my phone would normally be between 20-30% but last night I still had 70% after the usual 8hrs.. I think it's a big improvement for my phone and battery.

Are you using the stock, unrooted ROM?

I am using stock rom but the screen uses about 60-80% of battery life I am a very heavy user watching YouTube for hours and gaming so to be expected of any phone batteries life
---------- Post added at 07:03 PM ---------- Previous post was at 07:01 PM ----------
I have not tried any other batteries other than the stock ones I use a otter box case so. Most none oem batteries won't fit

Yep gaming and high screen usage will definitely kill the OEM V10 battery....

So I'm on the update I have ran it oem stock, rooted with magisk, and with root and test build of xposed, oem stock has a nice battery improvement, but with root/magisk moduals, and xposed I think MM 6.0 Had better battery life. I think this will change after the official release of Xposed for N 7.0

I never rooted my V10, is the battery life on those ROMS you mentioned better than the stock ROM?

I've noticed great improvement since I have the perfect environment for Nougat's doze. Flat on a surface, screen off for a period of time. I went from 5-15 end of day to 70ish. Those who have the phone in their pocket, or are more active may want to pair with greenify's option to make doze more aggressive to see better battery life.

Root has a small drain but, N 7.0 is awesome and even with magisk root installed its better than stock MM 6.0. If you ever went to using xposed then MM 6.0 with Xposed still wins in terms of running a modified system. MM only wins because its able to run a official build of xposed... I can't tell someone to get root If they don't know it well, but the new N 7.0 is a good update that adds batterylife

I've rooted several phones and tablets in the past, I haven't bothered to root my V10, been happy using the stock ROM

By rooting your phone, you get the ability to change stuff deeper into the phones software, which means that you can install apps that will do the trick for you. Some of them require Root access and some require even deeper changes to your device software by using xposed framework. By using such software you can stretch your battery life by too much. I remember i managed to get my One Plus One to drain just 0.3% (thats 13 days battery life without using the screen ofc) per hour, but it cost me some slow sync of apps like gmail, facebook, messenger, whats up etc. Thats because i forced these apps to check for updates once every 5-6 hours or so. So you don't have to use a custom ROM in order to get root or xposed framework.

So I use my phone like all day screen on time is like 9h.... I'm running the 10000mah huge battery that has the large. .7inch thick case it's on amazon. But any way my system hasn't been great on battery life since I use tones of apps and mods ect ect.... I am only posting this to say a few things. I don't like the unofficial xposed framework all that much on N 7.0 I love the update though my battery life is unstable at best. If you are going full out mod crazy like I am use battery saver ware it turns on immediately and run it all day. Some days I go all-day at work and still have 70% battery left by 6pm other days I run it down to 50% by 6pm... Without battery saver on though it's not good battery life. Right now I'm on Nougat with magisk 13.3 viper audio xposed v24 and tones of mods... With all the add-on stuff I am thinking something is using very low optimization.... MM was a little more stable and predictable if you are happy with stock roms then the nougat update plus running battery saver on full time should give really good results

Battery life
Yes man, in short the battery life of this device is completely, as you mentioned, "unstable".

s7 edge battery in s6.

hello.
how to "activate" s7e battery in s6 on custom rom (nexus os 9).
I changed the s6 battery to the s7e battery and I have the same time of work on one charge, max 2.5h SOT and 12h standby.
accu battery shown max capacity 1900mAh (like old one battery) of 3600mAh

First of all make sure your battery is original.
Then you will need a Kernel that provides S7 Edge battery funcionality. You can reffer to this site: https://duckyb.github.io/BatteryMod/links.html
There are methods listed to properly calibrate your new battery.
I've also made this modification, but I'm running 7.0 S8 Stock Port with Maritos V14 Kernel and it works fantastic. I get around 5-6h SOT with movies and other stuff.
Hope this helps. Good luck.

I'm currently using this ROM:
https://forum.xda-developers.com/ga...pment/superstock-s8-galaxy-s6-stable-t3714341
It's fast, stable and works great.
You can find kernel in attachment.
Don't forget to flash Magisk after kernel installation.

has someone tried to put the microcontroller on s6 battery instead of s7e battery one?

This.

Hello is this necessary to use this tool?

I believe that is just a standard lipo charge protection circuit that prevents the battery from going below minimum or over max. The s6 and s7edge batteries should have a similar circuit. I can't see clearly in your image but one of the chips should say DW01.

I have made this change. You don't need to do anything just let the phone run through a couple charge and discharge cycles and it adjust to the bigger battery. If you have not noticed any change I would simply say you probably got a fake battery of lower mAh rating. I noticed almost immediately. End of day 2 I had like 75% battery. The S7 edge battery is fatter though but cause I use a case the small gap between the back glass cover is not visible. If I were to do the mod again I would bond 2 or 3 pieces of paper together with resin. Let it dry and draw a perfect outline on them, then cut that out with scissors and use it as a spacer.

Could you take a straight on picture of that with better lighting. I almost can read the model numbers on the main chip. Bit too fuzzy to follow any traces.

hello,
I made the battery mod but after days of calibration, I'm facing a strange issue, my battery dies after being at 0% for 1 hour and the phone automatically shutdown.
But the phone still has battery life, I can leave it on android revovery menu for almost 4 hours, until it shutdown it seems that android doesn't seem to recognize the extra battery capacity.
What can I do ? Is there any patch that can improve the battery recognition ? I don't want to root.
My phone is unroot, stock rom.

Don't know why you don't want root. Here's my steps for G920F:
1. Install TWRP as recovery system
2. Install Ultimate Nougat ROM (with Magisk included so after this your phone get rooted)
3. install Martitos Kernel for battery
4. Install Magisk Apps for Root because Martitos might remove magisk.
Battery life of Samsung S6 G920F with S7 Battery is great now!

Can I install other custom roms out there? And just let the battery calibrate itself? My phone constantly gets hot with just browsing the internet.
I'm looking for android go custom rom.. Big battery + rom for weak phones might = days of battery life

To change battery capacity

General AccuBattery - S22 Ultra battery statistics

Hello.
I installed Accubattery some days ago to check my S22 Ultra (snapdragon) performance.
Since a few updates ago, It is not even reaching 5h SOT with 22h total combined use.
Everything on my phone is stock. Nothing done about "optimiziation". It doesn't make any sense to buy a flagship and use it as an entry-level phone.
My settings are:
- Mostly on Wifi
- FHD+ with 50% brightness and adaptve refresh rate
- No bluetooth or NFC
- No AOD
- Most notifications allowed
- No battery saving mode
Mostly use it for browing, social media and youtube.
Camera app is a battery draining beast when used.
To my surprise, the app shows my phone is around 4400mA of battery, and discharging performance is as follows. Has anyone ever used it?

All Samsung's should be optimized. 50% brightness is too high for indoor use; use manual brightness control and stay in the 30-40% range when possible. Cloud crap uses a lot of power in the background, Google backup Transport is a prime offender. 4G is more efficient for light bandwidth; make sure it's using 5G only for large data transfer bursts. If the download site is throttling data than 5G burning battery for nothing.
With 4400 mAh my N10+'s easily get 13 hours... and in actual usage they're only a fraction of second slower for most tasks.
I'm not pleased with Samsung today. No expandable storage makes you depended on cloud and/or external storage. A profound loss of balance and core functionality because of poor design. In part because Google scoped storage. I run on Pie and Q still. No 5G, variable refresh rate and the camera is less processor intensive.
That doesn't mean though that you can't improve your SOT dramatically.
This N10+ N975U/Pie I'm holding use to be a hot running hog, it's SOT was similar to yours... it sucked.
This is what it's doing today on a appropriately 3400 mAh derated battery that's nearing the end of its service life. A completely different animal and all modifications were done with a stock platform.
Until you put some serious effort into optimizing it you'll never know what it's full potential is...

You've only use the app for 7 charges. It's not enough data. Come back in a month to see where your battery health stands !

The Google Android bucket concept is a mess. Leave it on for 2 months and it still sucks. The results will be vastly inferior to one that was hand optimized. Google Android isn't that smart.
Manipulate the bucket states as much you like and on a fast phone you'll notice nothing. I played with it for months. It may work on Pixels but Samsung's are a much different animal.
If you actually tone down a hog you'll notice it within a day or less. Its going to take more insight than just flipping on global power management though.

I also have a SD s22 ultra (908e). I was getting terrible battery life. Get adb control app for PC and debloat everything you don't use ( i used uninstall option) I went from a shocking 4.5-5.5 hours sot to a consistent everyday 8-9hrs sot also make sure you put all apps that you don't need notifications instantly for in deep sleep manually.

In individual app settings disabling background data and battery activity doesn't invoke global power management.
Close out apps when done with them as some apps like Brave will continue to run in the background and can use a considerable amount of battery over the course of a day. Camera is another one to watch.
Use Device Care>storage>clean now as needed. The older 360 degree version worked better but should be firewall blocked if used.
Clear system cache; in general reboots do nothing that can't be done with the system booted other than the former. Needless reboots waste power.

Hey mate, may I ask which apps did you uninstall with ADB? I am worried to do stuff by my own because I'm not that knowledgeable when it comes to this stuff, and I don't wanna end up with a brick instead of a smartphone. I would be really grateful if you would respond Thanks!

Also, it looks like you only had 7 sessions of charge and that too the phone wasn't charged to 100%. Charge it to 100% a few times and you will get a better estimate of your battery health. 4400mah seems too low.

Maybe 6ish hours on 5g with WQHD and Adaptive motion really aint that bad.

Why does accbattery estimate the battery size at 4885. Thought s22u had 5000mah battery?

By usage. You can manually set it to 5002 mAh if you want. How accurate the absolute estimates are is unknown. However serve over time as a reference point.
