Hi I recently had a new battery put in my 6p. The original battery was only running at 63% of it's original capacity. That's according to accubattery.
So my question is what steps should I take to ensure the battery was indeed replaced. ( Because it seems like it is really not much better) I wiped the battery stats and use an app called l. Speed for battery improvements. I am running the latest los as of December 1. As of now accubattery reports 70% health. It's been 3 days since I got the phone back and had accubattery running.
Should I give it more time to get an accurate reading?

Like most of my fellow XDAers, I've been struggling with battery management issues. What apps to install, CPU hogs and all that jazz.
However, while I've been very pleased with the battery life I was getting from my U8800, I saw several guys complaining of horrible battery performance. I thought that they were just 'doing it wrong'...
I now wonder...
Since November I started noticing strange battery issues. Very fast draining, misleading battery readouts... I wiped my device, flashed it with pretty much all roms (custom and official) available but my battery kept screwing me. And its been worse as time gone by! I now hardly get 8 hours with at most 1 hour of usage.
I'm now posting this after calibrating my battery 4 times the day before and the first time I used our today my battery life went from 100% to 82% in less than 5 minutes! CPU spy reports 85% of deep sleep. Better battery stats has hardly anything logged. I already ordered a new battery but if this keeps going on...
Thoughts?

Why did you calibrate 4 times? How did you calibrate it?
Charge it to full, calibrate battery using app/recovery/deleting batterystats.bin, leave it to totally discharge, fully charge. It is not calibrated until you go through a couple of charge/discharge cycles.
So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?
hello can you help me wid flashing...i came from android...no idea of how to do it...

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.
Last week I got a new battery installed in my Nexus 4. I was using the original, around 2 year old battery, and I found it would drain very quickly below 50%. I had a shop install the new battery for me, I don't know if it was an official LG battery or not.
I ran the battery down to zero percent my first night with it, and have charged it at night ever since.
When I unplug the battery in the morning the battery percentage will suddenly drop down to 88-94% in about 1 minute. After this the battery drains normally and I get good battery life.
Today I tried charging it back up to 100% after it had dropped to 88 %. It charged to 100, and drained normally down to 95. Then, in a minute or two, it dropped down to 84, and has been draining normally.
Battery life is good, but the strange behaviour makes me think something is wrong with the battery. My question is: is something wrong with this battery, or is this normal behaviour? If it is, than I can ask them to give me a new battery. All this is with the stock ROM. I flashed 5.1 since getting the new battery.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?
Same here.
Are there any solutions for this issue?
I changed from Note 3 to s 6 edge plus recently
The battery drops 5% per hour overnight when not in use. If I go to bed with less than 40% battery at night I am sure to wake up with my phone switched off in the morning.
When in use with screen on, the battery drips one percent every two minutes. This is the worst battery life I have ever seen in a phone. I was a long loyal customer of samsung and this is my last samsung phone ever.
Extremely disappointed
Please post your battery stats ? so we can have a better understanding of your problem. I suggest you install 'Doze' which should stop unnecessary apps from connecting to the internet and causing your phone to awake from deep sleep.
Dear Akbar 11
Heres the battery stats....is it normal?
I had the same issue, and as far as I managed to find out, it is a bug in Samsung's kernel. Flashing Arter97 kernel solved the issue for, but do post battery stats from SmartManager. If it says 'Android' or 'Android OS', then you have the same problem many of us do.
I don't think it's a kernel problem. My android OS is very low 4%. Like zoolok said post your battery stats from settings, battery, battery usage
I have the same problem. Battery was great before I flash custom rom. After going back to stock I have big battery draining. I must stay on custom rom. With Audax rom and Skyhigh kernel i have great battery life.
You have either messed up something big or you have an app in the background that is eating up your battery like no tomorrow.
And the reason i say that is because i recently got this battery life on my Galaxy S6 edge+.
And this was taken 2 days ago.
Here i use the CRISSCROSS ROM, AudaxPro Kernel, Greeinify and Samsung's own 'Appoptimizing' feature (same as Doze in Android 6.0).
So my battery life is pretty awesome.
i have problem whit battery lose 25% when i sleep
This is a usual day with s6 edge plus
Any help?

i have this problem battery ... if u fixed it tell me how?
Well I was expecting Google Play Services to be eating your battery (which is quite common) but it looks like your Andriod OS is eating the most battery. I would uninstall Facebook and use the web version it always helps with the ram and battery furthermore, turn off location if you are not using it and check accounts which are being synced. These are the only tips I can give you as I have never seen Android OS drain so much battery.
Since a few days Google Play Store is eating up my battery: I go to sleep with 100% batt and wake up with 50%, if I check batt stats on top I have play store at 45%, with 5h active a d 2h of CPU.
Follows Android system at 5%.
Going crazy why...

You've charged your phone 4 times during that day. I can't see what's the interesting part here.
Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/
Here is one print from my screen on time and accubattery.
(Sorry for It being in portuguese)

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!
