[HELP] Battery Drain with OOS 9.5.11 - OnePlus 7 Pro Questions & Answers

I got a very bad battery life since I bought the OnePlus 7 Pro (1 month) and I try to reset my phone two time but it is not helpful.
My phone drops from 90% to 35% with 3h50m SoT and my last charging 13 hours ago.
Any advice/solution for this problem?

My MATE 7 is suddenly DYING

Hello,
Suddenly last night, my Mate 7 connected to its chageur HUAWEI seen at his expense decreased to 60% and in the day to 9, 15, 17, 25%.
In my home this evening I changed charger and the battery is constantly decreasing from 23% to 15%. Tomorrow he should not turn on again. This is worrying for a Chinese phone that less than a year of life.
I am now in charge but with 11% battery.
This will is there ever?

What's average battery life of Ace?

Hi, I bought used Ace 3 recently and my battery life isn't very good. It's cca 20mins screentime — 10% battery, so cca 3 hours of screentime (both stock and CM12). I wonder if it's just old battery or if its normal.
I can return the phone in 7 days, so if such battery life is normal, I'll buy Xperia M instead which is said to be better.
Thanks for answer, I have time just until Wednesday.
It's good, depends what are you doing with it.
So my it's problem of my battery and with the new battery will the phone last one day of moderate usage without problem?

battery life

hey guys, am I the only one.....
after the last update, my battery went to [email protected]!
Initially I would get a good 24 to 28 hours. No, I barely get 8.
No other chnages...???
Did you try restoring your device to defaults? Maybe formatting a battery will be a solution (discharge it to 0% then fully charge - do it 3 times).
I bought mine on monday, it updated as soon as I started it. First charge of course took a toll from me playing with the watch, only 13 hours. Second charge, took it off the charger at 9.30 pm last night, used it for about 2 hours, put it on "do not disturb" until 6.30 am this morning, only lost 8% battery in 9 hours.
Now, after 3 hours of normal use (not much looking at it and light notifications) lost 3% so it's roughly doing 1 or 2 % and hour. Not so bad if it stays that way.
I hope to get it to 2 days of normal use, if it gets me there, it's a solid buy.

P20 Sudden massive improvement in battery life

My wife has had the P20 from the week it was released in the UK. The battery life has been really poor, she is what I would consider a light user on a 4GB contract which she rarely troubles and with a tablet for use at home. She has taken to carrying a portable charger with her to make sure she got through the day. I had checked for any obvious drains, even turning off bluetooth, gps etc. But from a full charge in the morning, she would struggle to have any battery left by the evening, compared to me (a slightly heavier user) having about 40-50% left on my Samsung S9.
However at some point in the last week something has changed, she is suddenly going to bed with about 60-70% battery left.
Anyone else had similar? Has there been a significant update recently (to either the phone software or some other app)?

My mate 10 after a few updates, i actually use my phone to work, work 8 am to 6 pm get home and i forgot to charge the phone last night, woke up with 72% battery and was wondering if i should bother charging.
I think it has to do with the npu
I experienced the same after the last update. Before the update it would not last more than 4h sot with 1h voice calls. Now i can get 5h sot with 1.5h voice calls and still have like 30% remaining.
i have experienced increased temperature heat. dont know what is causing it.
Same here! But I just noticed it last night before going to bed (had it on full charge), woke up 8 hrs later and the battery only drained by 1% (only Wifi is on). Not even sure if the update was even downloaded without me knowing. But before this the battery for me was performing quite well, coming home in the evening with still 40-50% left.

Battery life after 1 year

Hi! I have an honor 8 bought more than 1 year ago.
The problem is that my battery never does 2h of on screen time.
I have oreo and I did a factory reset after upgrading to EMUI 8.
Do you think it's normal or there is something wrong with the battery?
