Battery Probem need suggestion...

Hi Every One I dont know from were i will start Ok
I have a Problem of battery its drain soo much even i dont use the mobile Much and its drain so much.
BaseBand is XXJPY
Rom is Unlimited Rom
Please help me what should i do

1. you should use the search function, there are quite good threads concerning battery life
2. you could post in the general or, even better, the Q&A section.
3. you should post your stats, just saying the battery does not last long enough is a bit vague, if you're used to a old nokia anything under 10 days will seem short
4. when did you flash the last time? the battery meter needs some time to be accurate again. to speed up the process let the battery drain under 10% and then charge fully. after 2-3 days you should get accurate results.
5. you can check the battery statistics in the settings an see what drains much energy (besides the display^^), if it's any single app you might wanna look for an alternative. You can also think about apps you have installed that need the internet for updates/communication. such as skype and facebook. Especially skype has not the best reputation.
6. what kernel are you on and has it tweaks (speedmod f.e. access able in recovery) you could enable?
7. Check what modem version you have ("baseband" in the settings -> about phone) and whether it's compatible with your region. a thread with information on that is linked in my signature.
8. To tweak even more you can try apps such as Tasker or juicedefender

Hmmm OK^^
First of all i used Darky rom wth frimware XWJS5 and Kernel (stock+Voodoo-Froyo-GT-I9000-XWJS5)
And now i install Same Firmware its (FROYO.XWJS5 Build Number) And i install Unlimited Rom 8.0
I see in Battery use the (Display take 60%)-(Cell standby take 18% Wifi take 15%)
Baseband version is I9000XXJPY
I install that Rom yesterday and i put in Charge When the battery in 4%
And Still i didnt install any Software like facebook or skype

If we say that we want like nokia Then its just sound like Nice joke But dosent work at all.
Here is only problem that i wont take much longer even i dont use jst power Off

well and how much time has passed since you charged and on what % are you now?
I guess the battery life will get better in a few days by it self as mentioned above

I Charge the mobile in evening at 3 when the mobile clos it self
So now the battery life is 85%

Wow. Unbelievably short battery life!!! Just like every other user here and all smartphones around....

what should do now any idea?

So you charge every day at 3PM at which point you have 85% left? Or you lose 85% over 20h? The later would be a bit much
Unless you watch lots of videos/play a lot on your phone. to make it easier:
a consumption of under 2% per hour on standby (screen off, just laying around) is normal. For reference values look here

now its 82% wthout doing anything

No offense taken.
Its just for a quite a long time now it was known to just about everyone that smartphones are very battery hungry and it is good to get a full day from one charge.
And yet we see still such post about battery. Kind of pisses me off.

Well in the case of osasih we have 85% at 05:25 and 82% at 05:59 which makes 3% in 34 minutes. That equals to 5.3% per hour, so that the phone should last almost 20 hours - that's fine.
However, in my case I see a drain of almost 9% per hour which is far too much IMHO. I logged yesterday when I left work charging until 65%. Whith 9% per hour it should have lasted until midnight, but suddenly it dropped from 33% to 2% in only one hour!

Yes right saying But some how it drain so much like if i listen songs yesterday i was listning songs and i fall sleep the battery was full and wen i wakeup the battery all most finish..and even wen i clos the mobile put the batter out and reopen it again so i see batter is 10% befor closing the mobile it was 53%

I'm going to assume that you read my post on the first site^^
try rebooting the phone and look whether the problem persists. I know it sounds stupid but I think there's a bug somewhere that eats battery after flashing or randomly after boots. I only experienced signs of it after flashing since I don't really shut down my phone on any other occasions

OK i will try to flash again and see how it takes but rather flashing will break the mobile isn't? lets try wth darky final rom 9.4

accubattery app says I've lost 15 percent of my charge./ health

Is this right.. Of so it means after a year I would of lost 30 percent as I've had the phone for 6 months... This surely can't be true... Damn I miss the replaceable battery..

What your daily batre statistics are like. If you can still 24 hours and about 4-5 hours sot it is still good and in tolerance

Thanks battery still good... But to lose that much in 6 months not good

Hello i have also an issue , i had always used built in device maintenance feature , and it always told me after 100% charge, remaining time was about 20 hours, but for 2 days after full 100% charge, device maintenance tells me i had 12 hours left after full 100% charge, this is weird , i had done no change to any setting , except installing some games which i play , but why they reduce battery timing if i don't play them ? only installing them reduces battery time ?

Well i do not know for sure about this, i hardly ever use fast charging and i do not feel the battery drop since the first time usage a year ago. I can still use within 24hrs and get 8-9 hrs sot

I lost 28% in one year. Really says a lot about the quality of these batteries in the S7. By comparison, after a year my S6 lost less than 10%

Do you factory reset after updates? Use package Disabler? What's your cure?

Not at all for both. I am in a custom rom actually

no one gave me any answer ? please i need to find some clue about it, why built in device maintenance feature says my battery life is only 12 hours after 100 % charge ? just few days it was telling about 21 hours left , i do not made any changes , just installed few games, anybody has a clue ?

I love the Accubattery app and use it in all my newer phones..It's education is spot on too..
Most people fully charge there battery everyday..Going over 80..Or 90% regularily, especially 95 and 100% having phone go to 4.3-4.35v is just plain bad for the overall battery health of a lithium ion battery..What it will do is degrade the longevity of the battery where as normally one should get 500 cycles to get to 75% health left it will get there much quicker and I see so many that have phones, like this one and other non replaceable battery models that have toasted batteries within a year..Toasted as in the life is much shorter and drains so much quicker and needs recharge by 2-4pm..
As for fast charge..Jury is still out..Battery researchers say at current levels of less then 1c fast charge rates it shouldn't make a difference but I say it does..At least a little..So I only use it when needed..Once or twice a week (and only up to 85%)..
But outside of that..Even when handled well,some batteries just aren't up to snuff and die quicker..

Just curious are iPhone batteries better or they too lose the same percentage charge per year... Or it it Samsung just using cheaper batteries

They are about the same and like all lithium ion's, will suffer same fate from over voltage (100% charges all the time)..And actually apple batteries seem to fall off a cliff sooner then most..We all know people with iPhones (that are older) that will hold far less a charge and many that hit 50% and die needed recharge immediately...Is what it is..
But if u do things right one can extend the overall longevity of a battery by a fair bit

Another thing to keep in mind and very few know this about the S7 Edge (and u can search and confirm this online and with Sammy),is that the real (useable) capacity of the battery is 3521mah and not 3600mah.. and this is because it is a 3600mah @ 4.4v battery but Sammy locks it out to max at 4.35v (which is actually a good thing for safety and to help with overall longevity of battery life thus reducing the useable mah to 3521.
So in my Accubattery I custom set my battery capacity to that 3521mah number.
And on a side note..I wish Sammy and phone manufacturers would build setting into the kernel that would allow a user to set a charge limit (say 80/85/90% for example) that would stop the charge or just trickle when left plugged in and not have it force it to 100% and keep trickling it at that max ...That is actually the main cause of battery life killer..Plugging in at night..Gets to 100% quick then has hours at overvoltage (plus higher temps) and those two things alone are 95% of cause for lithium ion killer

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Huawei Mate 10's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

the best that I got with the mate 10 pro EU was 1% lost in 9h15m. this was a couple of days ago. I will try to recreate the scenario and I will post a screenshot.

4-5% for me here 8hours standby.

Same here

Flightmode? Wifi on? GPS on? Charge-Level of the Battery?
Mine loses 5-7% in 8h in Flightmode, without Wifi and GPS on when in the 70% Level. Maybe it would lose only 1% when fully charged because the battery gauge stays at 100% for the first few % of drain (~ 100mv on mine).

Can everyone here note whether or not they've rooted their phones or not. I'm trying to determine whether the AI is assisting people with their amazing standby times/battery life because when you root, supposedly the AI doesn't work properly any longer

I'm rootless. Phone is sleeping better than me.

pretty impressive
Mate 10 PRO
I have lost ~0.4%/h with dual sim cards from the same carrier.
Official rom, no root
WIFI ON, MOBILE DATA ON, LOCATION ON (high accuracy), LOCATION HISTORY ON. all apps in the background were closed/cleared.
It was 95% after 11 hours, the screenshot shows 94% because I have forgot to take the screenshot and I have used a bit the phone.

Yes that's really impressive and similar to what I'm getting. What other users have reported (and also in my experience) is that the battery meter takes a much longer time to drop from 100% to 95% compared to maybe 80% to 75%. You can try repeating your experiment above but start when the phone is 80% or 70% and see if you still get the same rate of discharge. I'm curious to know your experience. Cheers!

I will try that also but next experiment is to activate the data saver from: settings --> Wireless & Networks --> Mobile data --> Data Saver change from OFF to ON.. I want to see if this helps a bit...
edit: to see if it helps even if the WIFI is always ON

Guys, give the phone some time to improve performance and reduce battery drain.
The NPU runs when the phone is in standby so, on the first days it's normal if the battery drains faster. If you are changing phone settings all the time, the NPU unit will try to optimize it again.
Also, the latest firmware from HUAWEI improved a lot the battery.

Mine lost 1% last night. All on as usual. I guess if you remember to closely all apps that help...

Idle battery drain

Idle battery drain is driving me crazy.
I've got three phones here for comparison, the Essential, an original Mi Max, and a Mi Max 2.
The Essential is on the latest 7.1.1 firmware, the Mi Max is on a 7.1 AOSP based ROM (RR), and the Max 2 is on stock MIUI 9 (7.1).
All three phones are running the exact same apps, same apps doze optimized, same features turned on, and everything else exactly the same. Same wifi network, same email polling time, same messages delivered each one, same wifi calling enabled.
Average screen off battery drain:
Essential: 1.4%/hr
Max: 0.3%/hr
Max 2: 0.2%/hr
It's not completely fair to compare per hour drain because the battery size difference. Normalizing the battery size to the Essential phone:
Essential (3040mAh): 1.4%/hr
Max (4850mAh): 0.48%/hr
Max 2 (5300mAh): 0.35%/hr
So the Essential is draining approximately 3x as much battery during idle, and I really am expecting something like 0.5% or less per hour.
What's the key to battery life?

Same problem, came here to see what is up. Looking at the graph, it looks like it took a while for the phone to go into deep sleep, but even using better battery stats, I can't peg down where all the wake time is coming from.

I am on Android 7.1.1 NM181C and have .03 per hour idle drain.

Something is keeping the phone awake with the OS being awake for 8 hours! You need to track down a rogue app I think

Currently I'm only using all Google app except what's app, Facebook and telegram. Not even 30 apps
Could any setting can also drain OS ?
Thank you for your reply

Your comparison of the 2 phones come with 6 series processors which are known to have way better battery life than the 8 series SOCs. You get better performance with the 835 vs the 625 by a long shot but you get battery life.
The battery life on the Essential is fantastic because of stock android and the best for that processor I've seen out there.

I'd try uninstalling Facebook and telegram where possible! Facebook for sure to see if that helps

I've found something interesting today after reading 100's of post about battery drain. Most of the time my type c to 3.5mm adapter is always connected to my phone at nights.
And I've seen the message 'USB supply power to attached device' Thought that message in status is irritating I ignored it and I found out that is the culprit which doesn't let my phone go to deep sleep.
And I tested this using 'CPU spy'.

Ive been experiencing a battery drain myself. A couple of nights ago i took it off the charger at 100% about 5 hrs later it was at 88% and the phone was sitting idle the entire time and i closed all the apps that were running.

Same problems here with Oreo beta (NMJ32F). This night, I got 20% off during the night (8h) with airplane mode on; you can find battery historian capture attached.
Although the battery historian has overflown, note that BLE scanning is always on during the night and, moreover, I got lots of kernel wakeups (not userspace) due to the following concept:
Ranking Name Duration / Hr Count / Hr Total Duration Total Count
0 Abort:noirq suspend of c171000.uart device failed 46m53s294ms 5066.45 10h57m56.452s 71093
So CPUs are always on... Let's hope for a fix soon!
Best regards,

I'm having the opposite experience. I went to bed last night at 94% and woke up 7 hours later at 93%

I go to sleep and not surprised if I don't lose any percent...

I've been seeing 22% drain over night if I turn my WIFI on

is your essential share diagnostics on?

I have the same problem with my essential, I charge it to 100% and go to bed, in the morning the phone is on 94% sometimes 92% and it's driving me crazy ?

You serious? Assuming you're sleeping 6 to 8 hours, 6% to 8% is literally 1% drain, and that's great. That's 100 hours of standby, and that is totally acceptable for a high-end phone. The other guy is getting 10% drain an hour, that's a problem. I'm getting a little more than 1% drain on idle, but I charge over night, but I still have between 40% and 60% battery left by the time I go to bed. My OPO would have about the same when it was new with COS 11. By the time it broke (3 years later, and on Lineage 13) I would be 10% if I was being conservative with its use.

Battery goes from 17-15% to 1% or 0% in a few moments

Hi.My wife has an s6 edge+ from 1 year and 8 months or so...The thing is from about 2 weeks the battery does some strange things.It works well and charges to 100% but when reches 17 or 15% after a few moments it goes to 1% or the phone gets off without battery.I did a calibration with *#0228# and at the first time showed 86%.I charged it again till 100% and worked fine for 1 or to charges.Now it happens again...
It is firmware/software thing or the battery is bad?Need to change the battery?Thanks a lot.

Battery wears after sometimes.So i think its time for you to change the battery...
U can download an app called AccuBattery to check the current battery capacity of your phone

Ampere says: "Good battery life" and accubattery shows same charge like the phone.Nothing strange...

After a while the phone went well but now it does the same.In the morning it was at 8% i put it to charge and saw the battery went down till 4% in a moment.It doesn´t happens all the time,only randomly.It is the battery or the system?I need a wipe?

Probably battery needs replacement

May need calibration. This happens a lot after flashing custom roms. Download Battery Calibration from Google Play.
