Poor battery no matter which rom

I've been using several different 7.1.2 roms and battery life has been atrocious. I use wingoku 4.1.
I pair my smart watch to it but even when I use wifi (no bt) its bad, draining quickly, last checked about 22% per hr. Even with screen off listening to podcasts it still will drop a lot more than it used to.
I really don't have much in terms of stats. Honestly I don't obsess much about it normally but now its noticable.
Aside from suggesting another rom & kernel, would I benefit from formatting data and starting over?

Install accubattery and run it though a few charge cycles, it will be able to tell you the life left in your battery, it's possible that you have the same issue many of us have had with a degradation of the battery.

Yea. Thats my biggest fear. Ive replaced small parts before but my eyesight isn't as good as it used to be so Im afraid I might mess it up. Plus I'll need to buy a heat gun.
I'll be more than a little pissed if the battery's shot. This phone is barely 14 months old. Either give us a decent battery or make it replaceable.
Thanks for the info btw. I just installed the app.

Update--Im switching things up a bit. Recently I made some changes and this time I flashed a new rom without some of those changes.
1. I had switched from Action 3 to Nova
*HIGHLY doubt nova is eating up my battery so Im still using it BUT I did remove a widget that has weather. Since I keep phone on device only location, I think theres a chance its always trying to find my locale and consuming battery.
2. I didn't add a gov profile yet.
3. This is the first time in about 4 or 5 rom flashes I didnt flash CTT Mod.
* Again I doubt this is causing battery issues but Im gonna hold off flashing it. No throttling thus far.
As suggested Ill be monitoring with accubattery for a few cycles. But been using my phone about 90 mins this morning (at least 90% of that time actively using with screen on) and I've lost 13%--a huge improvement from yesterday.

Accubattery for the proof. New battery for the fix. You could always buy online and have it installed locally. Read up on where to score a good replacement battery, rather than another dud.

Its not really giving me much info yet. Because of my schedule throughout the day Ive charged periodically so I have enough juice in case I need it. Do I need to let it run lower to get an accurate reading?

Best to let it run below 20% at least and then fully charge until the APP tells you the battery is full- not your phone. Don't unplug until Accubattery says it is full. What you will observe is that the phone will continue to charge for 45 minutes to an hour past when the phone itself is reporting 100%. You will find the estimated capacity under the Health tab. Once or twice below 20% is enough to get a close approximation. After that it will move a couple percent max. You will know soon enough.

Well it turns out my battery is in need of replacing.
I let it run down like you said. I was going to go further down but once it hit 20% my phone turned off. I plugged it in, opened accubattery and it said 46% under health.
But I just checked again after charging to 100% and it now says 63% (2182 mAh total capacity).
I checked my imei on the Huawei site and my phone is 3 days out of warranty. Im hoping to get them to fix it.

Well sorry to hear that. Good luck to you on the RMA route. If not, the Cameron Sino brand replacement is a bit more expensive but includes a working battery temperature sensor. It will make your phone like new. Note in the thread I referenced above, some parts may get scratched/cracked depending on the skill of the repair person. They aren't expensive so it you are intending to keep the 6P for a while longer, it may be worth it to buy those just in case.

Thanks for the support! I checked that thread and didn't see specific parts (inexpensive ones you referenced) If they're listed Ill look again. It doesn't seem too daunting. I was able to replace the screen on my son's WiU controller. Those were very tiny parts and YES--I did snap off a clip, however I was able to fudge it and it's still working about a year later.
Far as RMA, does anyone know if they replace it with the same crappy stock battery? From my perspective this seems like a clear case where a recall is in order.
But if its the same battery, Im just setting myself up for the same problems 8 to 12 months from now. Even if I buy a new phone Id still want to sell this one and thats not as easy with a crap battery. Plus theyd have my phone for x days so Id need to find a temp phone in the meantime.
Don't mean to jabber on...this sucks.
Oh yeah...cuz it was after hours I sent an email to support last night. Do you think Ill get a response? Or should I just call when I have time to be on hold?

Spoke to a clone at Huawei then asked to speak to the clone's supervisor (wasn't sure if clones had supervisors--they do. But the programming is identical.) Long frustrating phone call and they aren't going to replace my battery because its out of warranty...by 4 f#@&ing days!
I told them they lost a customer for life and I was being 100% sincere. How could I ever buy from people who thinks it ok to sell defective crap, know about it, then do nothing to make things right?
I'm gonna replace the battery on my own. Whether things go good or terrible, one thing is certain--itll be the last time I ever replace anything on any product made by Huawei.

Axon 7 custom rom with best battery life?

Hi all!
I have been getting bad battery performance on my axon 7 for as long as I can remember but didn't really want to try custom rom because I'm afraid it will void warranty. SOT reported with GSam is 2h30m. Fast forward the phone was water damaged and fixed locally so my warranty is voided anyway. So I think it's time for me to try out custom rom.
My main concern is battery life then functionality. Any recommendation for rom & kernel would be much appreciated! Thank you very much!

You might have to replace your battery . I did mine myself in about a half an hour . Batteries are cheap and the fix is relatively easy.

Guy above is right. But I'd like you to try something. Before changing it, use Accubattery to see how much capacity your battery had. After 2 charges you'll have a pretty good idea of how utterly destroyed it is. I managed to get 7 hours of SOT when the phone had about a month of use, now I'm getting 4:30. My battery says 2400 mAh.
Also, there's a bigger battery going around, a Losoncoer 3650 mAh battery. It's reportedly the same size and all. If you happen to try it out, let me know. I want to change the battery and i still haven't decided whether to buy one of those or an original one.
For comparison, the original one is 3140 mAh

you don't if you don't want to, and how would you not see the improvement after basically doubling (or more) the battery capacity?
Maybe you'll need to download a battery calibration app, those basically delete the calibration file and the phone should generate a new one

I bought my phone used in January. I was told it was a little over a year old . It was immediately obvious to me that the battery had issues and I had no insight into the charging history . Accubattery pro told me the capacity was just over 1800 mAh or 58%. I just rebooted after the install of the new battery and now it's it's back where it should be and working great.

Lol what. Accubattery is just to get the capacity estimate. After using it you should just decide whether to change the battery or not.

My battery is at 1700 mAh or 55%. I guess I'm replacing my battery first then. Is there any advice as to slow down battery deterioration process?
Edit: back to the custom rom question, does it make much of difference on battery life over stock?

Yes to both. First, charge the phone only up to 80% or so. that will prolong the battery lifespan about 3 times. There's a mod that can be installed via Magisk, that automatically stops charging when it arrives to a given percentage, then starts charging after it uses a couple percent.
And custom ROMs can be much better in the battery life department, but not always. In my case I get about 4.5h SOT on stock and 5.5H on Oreo AEX
(My battery seems to have 2400 mAh, also want to change it, but I have completely decent SOT)
P.S. Please do tell me if you buy a 3650 mAh battery. I'm thinking on buying one of those. They say that they are the same size than the original ones. plus they are not that much more expensive

What rom are you use right now? I get about 3.5 to 4 SOT on stock. Considering to flash AEX, but I not sure it worst it - stock rom have pretty good camera, spearker, "google now on tap" which is very important to me (google assistant hater)
The 3650 mAh is completely fake. I think it is impossible to place a bigger battery in the same space in the machine

S8 battery capacity shows only 1500mah from 0 to 100%

Hello,
I have recently purchased this little usb battery capacity tester. I have used it on my 20000mah power bank and it showed me a capacity of around 16000mah. That seems realistic, considering that I have used that power bank quite a few times for a couple of years.
I then decided to test my S8 battery. I fully discharged it twice, to make sure that no mistakes happen, and then charged the phone while it's off. Made sure I am charging just the battery with no power being used.
The result was a little bit disappointing. I have gotten 1494mah ... Is that real ? The device clearly works, but the phone was bought last March. It's only 8 months old.
Any input will be helpful.
Thanks
Ps. Seems I'm too new to attach the image, sorry

My S8 shows 8 cycles and 2733 mAh.
Phone is almost 2 yrs but I never (well, almost never) let it drop below 40% and as I understand it a cycle starts when the phone is below 20% - but correct me if I'm wrong.

I'm pretty sure 20 is the magic number. I did I looked at mine and it it's like 1471 x2 and my wife's capnom was exactly the same....
my phone is almost 3 months older and she charges sometimes 2 times a day so I don't believe those numbers are for checking capacity. But for something else.
I'm limited to the 80% charge by root and I never drop below 40% so the cycle thing I believe it's accurate

Yeah it's to random that's why I say I don't think that's what this is

Any battery monitor app works?

As usual, BetterBatteryStats and Gsam Battery Monitor are among the first apps that I install on my new devices and I often use them to check what apps are eating my battery. The two apps worked perfectly on my non-rooted S9+ running OneUI (Android Pie) with some extra adb commands, but on this S10+ they both don't work; BBS says "No stats have been collected yet", GSam is laggy, only shows the %1, %0... and drains my battery like hell during screen off (4-5%/hour).
So has anyone succeeded in making any of the two apps work? Or are you using another app with the same function?

Thanks for opening this thread. Yes, I am having the exactly same experience like you.

I am experincing the exact same thing!
Thought I was going mental.

I'm running AccuBattery and CPU spy reloaded, both apps report that my phone never goes to deep sleep, but I can't define what causes it

The actual values seem to be fine, though. Mine uses under 1 percent per hour over night after disabling the sonos app - it is a disgrace ever since. Exynos, 512GB S9+.

I'm running accubattery and in my case it DOES register deep sleep. So the lack of feel sleep for some might be caused by another issue that actually blocks the phone from deep sleeping

had the same issue no deep sleep. but this solved the issue for me follow this steps.
go to settings - general - reset - dont factory reset - but reset all other 3 options. 1-network reset 2. accessibility reset. 3. all settings reset then redo the settings as per ur liking it ll fix the issue.

Same issue here, glad I'm not going crazy

What is your messured battery capacity? Mine is 3650-3700...of 4100...wtf?

I had this same issue, and I uninstall accubattery, install it again, and reset the battery calibration reading using that code after I cleaned system cache on recovery *#0228#, yesterday I decided to turn the device off as I though my battery was going full crazy downhill drainingtown (joke) and turn it on, left it on airplane mode overnight with bluetooth on, and it has not stabilise and accubattery does report deep sleep. Also I check the battery every 2-3 hours to see how is the drain. Running since 5 am european time at 34% now at 11% and it is 11:45 AM european time as I write this post

If it's based on charging from like 60 to 100, or 25-85 % and so on, it will only show you some rough estimates, far from real capacity possibly. 1-100 % charges are far more accurate. For what i see, Samsung is bullshiting with the 4100mAh capacity, or controller software is limiting it to about 3700-3800 regions. In the menu it clearly says- 4100 typical and 4000 minimum capacity...

Don't forget the basic li-ion battery rules, one of them is that at least 5% of your total charge will be kept as reserve in case of overdraining, about 200mAh of your battery in this case are there to keep your battery rechargable, every battery powered device works like that, no need to accuse Samsung of anything regarding that aspect.

Sure...but i messured 3500 mAh on phone turned off...bit too much of a difference, hm? On the other hand, messuring iPhone 8 gave me almost exactly what was stated , the same with 20000mAh powerbank, messured even bit more...so i'd just encourage others to test and compare. 3h20min SoT also seems weak tbh...

True full battery mAh

Has anybody tried tools like Accubattery etc to determine the true mAh of the battery?
I get around 3100 instead of 3700 and it has been there almost since I bought the device

Yes, mine shows the same. It has shown around 93% since I got my phone. There's another post with several people claiming the same.

Accubattery does not work for showing an accurate battery % on the OnePlus phones.
Well known issue that has never been addressed, so don't use it for that.
You could manually set the battery size to be the same as it is showing to monitor wear, but that's about it.
