Battery Issues

Hi All
I bought Nokia 7 Plus yesterday and set it up, but the battery drain so fast. I left my phone to sleep with wifi on throughout my sleep it drains 10% with just pushing notifications from FB, like everytime I will get FB Notifications and not open it it will drain 1% of the battery.

Remove fb and see magic

U just answered to your question. It's not the phone, it's just crappy facebook app.

Facebook Lite is the way to go if you need FB, I think - normal version eats battery a lot, and I'm not sure if that will be fixed at all - seems like they don't care.

If you have to use Facebook, use Facebook lite or alternative apps like Friendly.

Hi, I got Nokia 7 Plus yesterday and started using it today. Initially with the battery percentage came with package, battery draining was slow. After doing first charging from 21% to 100%, battery is draining too fast. It is common for some batteries and takes some charging cycles to get battery optimized. If battery draining is happening too fast even after 3 to 5 charging cycles then there would be some fault with battery.

I got my phone day before yesterday & its now running Android 8.1 with the May security patch. Since the time of use, I've charged my phone only twice & both times charged it up to 100%. I feel the batter is draining. Please have a look at the screenshots and let me know if the battery consumption is fine or its draining fast. The battery dropped by 1% in 4 mins of the phone being idle with the display closed. Also the stock camera app is consuming a lot of battery.

I can confirm a very hard drain, too. No way to reach 7-10 hours of usage.

i'm getting about 5-5.5 hours of sot with moderate usage... Checked the app usage..where it shows PUBG used 12% battery in 38 min, 45 min of youtube drain 8% 26min Instagram drain 5%...I don't use fb much on phone when needed i mainly use fb lite... .i don't use auto brightness. so my brightness level is always 45%.. in overnight( well it's like 5-6 hours) battery percentage dropped 4%.. Wifi is always on and GPS is always on high accuracy.. in power saver 19 apps are allowed for background activity...

Battery drain
I just purchased my phone yesterday and used it for some time. I put it on charging at around 20% and didn't use it until full charge. After it got completely charged and then I just used it for few mins it went down 100% to 95% very fast; later after few mins I started suffering net and did misc stuff for about an hour it went down to 85%. Next morning I saw the battery % was 81%. Is this normal? I mean how can it last for 2 day as the company claimed. Aslo I am android 8.1.0

This has been a comman issue with Nokia 7 plus, including me. My battery had high discharge rates in both Oreo and Pie. However, post March security update, I am seeing some good battery life. I would also suggest to update to Pie and update Device Health from Play Store. Hope it works out for you.

try letting the battery drain to 0% then charging it to 100

TA1062 with build 00WW_3_51F here.
Before the march update, the phone could last for almost 2 days with moderate usage.
After the march update, I barely have 5 hours of standby time, and like 2 hour of usage time. This is crazy ! Not heating, but also randomly shuts down while it says like 65% remaining battery. I haven't changed anything else !!!
Does anyone have any idea how to improve this ?

[HELP] Battery Standby Drain (over night) 2% per hour - No wake locks - incl. GSam

Hello. I need some help with my new (like 3 weeks old) P20 Pro (single sim, no root).
I'm really happy with this phone now except for one thing. That thing is Standby drain.
I lose like 1-2% PER HOUR over night, doing nothing.
I left my phone last night on 25% and went to sleep.
Next morning, 7 hours later I was on 13%, losing almost 2% per hour.
In my opinion, that's just too much for doing nothing on the phone.
I'm not an expert reading those battery stats, but I dont actually see a problem.
There are no wake locks and the only apps that use the battery are Android-System, Kernel (Android OS) and Google Play-Services.
Huawei Health and Google Play-Services used the Sensor time a lot, but I don't know if the sensor time is important for the battery.
If you have a solution, please give me an advice.
My dad gets the same phone next week and I wanna get it done untill he gets the phone, so I can do the same.
Things I've done:
- wiped cache
- reverted to factory settings via standard recovery
- debloated (like 15-20 apps)
Screenshots:

TOP 3 Battery Use Apps
Network + Sensor + Hold Time
Big thanks.

Trust me, you're experiencing the same thing I have been for the last 6 months. It takes around 3 weeks or so for the phone to learn how you use the battery and from what people have told me on XDA, Reddit and Telegram, this battery drain is "normal" which I still don't believe. I had a Redmi Note 5 Pro before this phone and it probably drained only 2% overnight over 7 hours and I could hit SOT of near 11 hours on a single charge so idk what Huawei has done with the battery optimization of this phone as my Note 5 Pro also had a 4000mAh battery like this phone.
All you can do is continue using the phone and hope it stops soon or maybe think about replacing it with a better phone

High Battery Drain on 11.0.4.0 Global

Since upgrading to 11.0.4.0 Global (QFKMIXM) my Phone is draining heaviliy - have to charge it daily with moderate usage (abt 1,5-2 hrs SOT, mainly surfing & mailing).
Already did a factory reset - no change
Can anoyone of you confirm this behaviour ?
Any hints to solve this issue ?

That's really strange. Look for apps that may be draining your battery. In my case 7 hours SOT with the same usage.

I never had a problem with battery with any update.
I get 2 days battery with 6 hours of screen on time and a couple of hours of podcasts and/or music playback a day.

Dunno if its helps you but im running Evo X with 11.0.4 Vendor/Firmware and yea im almost getting 7hrs of SOT.
Tho i used to have only 4 SOT before, but then i realised that it was due to Live2DViewerEX that was preventing the phone to go into deep sleep.

Update
First - Thank you all for your support !
After factory reset it took a few charging cycles and now the situation seems to get better.
Espacially overnight drain decreased and i´m back to normal (about 2 days usage and 5hrs SOT)
:good:

Battery life on MIUI 12 (EU)

Typically if I take my phone off charge around 8am and don't use it, I still have 94% or more battery left by lunchtime.
Updated it to MIUI 12 last night, today I took it off charge around the same time, right now it's 1pm and I have 61% battery left.
That's a horrendous change. If I was using it I don't think I could see a full day out now.
This is a vanilla Mi 9 on stock everything, never fiddled with.
Anyone similar experience yet?

Miui 12 has the worst battery life, sot and usage time i have ever seen. I tried the beta for about 4 weeks, stable just a few days but its the same. Xiaomi should never published this as "stable". A lot of users had those problems with beta for weeks and reported it but nothing changed.
I switched back to miui 11 just for not killing my battery within months.
Edit: testing 12.0.2 and it looks like they solved the battery drain bug with this update

I'm on Xiaomi.eu Rom (latest stable MiUI12). Battery life is nearly the same as MiUI11.
MiUI11 end of the day: ~30-35% remaining tipically
MiUI12 end of the day: ~20-30% remaining
So for me this is not bad for the first MiUI12 builds. First MiUI11 builds were more worse for me...

The worst battery drain I have ever experienced. Its good on standby, through the night goes down by 1% but during the day I lost 70% using google maps and data for an hour. With miui 11 I would have used maybe 20 max. im gonna root my mi9 and go back to 11 cause I dont think xiaomi is going to fix it any time soon

I've seen it so many times before... Once the phone is not the top flagship in OEM portfolio they don't care about the quality of the update. I don't think it's ever going to be fixed. Get used to it or go Custom ROM

Happens only on the first day of upgrade from MIUI 11. The next days are even better. It's easy to pass full day (normally I got around 1.25) with around 5-6H SoT.

For me it's just impossible. It's easy for me to get high SOT when I watch something with screen on all the time but it looks like phone have a hard time getting into deep sleep mode so it hurts standby time.

Weird. We all have different problems. My mi9 goes into deep sleep without any problems. I can also get 6h screen time but when I use data baterry goes really really fast. I can easily go from 100% to 10% in 3h using only google maps :/

Yeah battery drain on miui 12.0.2 is awful. my android system usage stats is about 43% right now? and they also remove Override Force Dark Mode option from developer options which was so usefull for me? we probably haven't need IOS notification style!

Battery friendly ROM

I'm using xiaomi.eu 12.0.5 QFACXNM and the battery drain is brutal: 11% battery drain at night in 9 hours without touching the phone. No airplane mode, but wifi and data off.
I restricted almost all apps at background and problem is not solved. I'm doing 3h SOT or even less at day.
So... what's the rom with the BEST battery and the best SOT? I don't mind the other features, if it's AOSP I appreciate if I can install ANX camera and GCAM (both).
Thanks.

I had very good battery results with PixelExperience - around total 40h with 3h screen on time (yeah not heavy usage). Right now I'm trying PA Q5

3h SOT is not a good result, don't you think? I was expecting something like 5h or 6h of SOT with a normal use... I know with 3300mah battery it's complicated but I don't use my phone with heavy apps, I don't play, only use instagram, photos, twitter, whatsapp/telegram and stuff like that...

I recommend PA.

for a 40h+ total with bluetooth location and wifi always on I'd say it's a very good result

I'll check both. I fully charged my phone this morning. 7 hours later, without any use (check my instagram and twitter couple of times and responding some whatsapps), it dropped 10% (to 90%).. At least six and a half hours were in deep sleep.
I think this isn't normal.

That also can be a signal for a dying battery as well. Approx. 1 % per hour in combined usage is a good average for AOSP ROMs. At moderate use, similar to your profile, the battery here last for four days with 4 h SoT. 8 h SoT over two days is possible but not what I reach often. Mi9 is running PAQ5.

I was thinking the same. At this hour, less than 12h after the last full charge, and with no use at all cause I'm currently working at home, so I use computer (like I said, watch a couple of times instagram, reply to a few whatsapps and check twitter a little) battery is at 80%, with 30 minutes of SOT. Something is wrong, and maybe you're right about battery.
I'll try PAQ5 and crdroid with quantic kernel... despite I like MIUI, but xiaomi.eu is an extreme battery-draining rom...

My Mi 9 is running several AOSP ROMs since more than one year. Since then I've simply no idea about Miui and its battery consumption. Tbh I'm not too much interested in battery life at all. I'm not an outdoor guy having access to a power plug only once in a while. I'm living in an area where power plugs are widely available. So running out of power is not a major threat to me.

I usually have a charger near, but it happened to me that, in a long session of photos, or in a heavy use outside my home or my work, battery dies more sooner than later... and that sucks.
For example, watching forums or instagram, it consume 1% each 5-7 min, and more of that, instagram and web loading are not so fluent as it should be, so... I'm gonna try aosp for a while.
Crdroid, Paranoid and Iodé OS seem the best choices, I'll give a try to the best battery-saver rom...

Changing ROM only might not solve your battery problem, if the problem lies elsewhere. I use the same ROM and I could get 4-6 hours SoT per charge, over a day of use or so. This is a 1 year old device so battery is no longer 100%. If yours is newer but you get worse result than mine, then it's something in your configuration, not the ROM.

Sure, in these cases I usually carry a power bank with me. Actually I can't recall when last time my phone totally went off power.
For the AOSP ROMs I can't tell about battery behaviour. Things like SafetyNet, banking app and G-Pay are so much more important to me that I never considered changing the ROM since PAQ5 does simply everything I need.

this phone has some hardware issue with the battery, some chip is not properly registering/measuring. You have to "reset".
I have more than 8h screen on time 0~100, and I have the phone 15 months.

I got same problems with you and in my case. I found out that my mobile signal was not stable, then phone auto switch network try to find 4g -3g -2g and it happened couple of times. When I' back to my hometown, battery is only down 2%.

I was thinking the same, battery duration is ridiculous. Last night, 1% battery per- 5-6-7 mins using kiwi browser/instagram. And 10% battery out last night with wifi and data deactivated. Now I have 56% battery with very few use of the phone. Charged it 24h ago.

I don't have a powerbank, I think I should buy one... Like I said, I still have problems with Internet, instagram stories and some webpages load slowly even with WIFI, so maybe it's a ROM problem...

I live in a great city and and I haven't gotten out of it since the pandemic started, so I don't think that's the problem...

I have miui 11 .eu rom, I have a post explaining how to get 8:30h sot
Your problem is xiaomi crap that are draining your battery and making the phone not measure it correctly.
Xiaomi programmed obsolescence on battery
H, since I updated from miui 10 to miui 11 and even now that I have miui 12 I have noticed that the battery doesn't last as long as before. I state that since I purchased the phone (July 2019) I have always charged the battery in the best way...

Hello im using miui 11.0.6 with a new battery and i get 4:14 on SoT, what version of miui do you use?

I on my xiaomi mi9 I installed the battery increased by 4000mha, I changed the kernel values with a file manager by making the phone read the same battery capacity and I do six hours of display on! To do this you must have root permissions and buy 4000mha battery ...
the path to take with franco kernel manager is:
/sys/class/power_supply/bms/charge_full"
/sys/class/power_supply/battery/charge_ful
Through a file manager, that is the path to follow to edit the file
