Poor battery life after last official update - OnePlus 5T Questions & Answers

Hi guys! I'm having very bad battery life after the last ota. I used to charge it every night but with something like 50% battery.
Since 4 days I have to charge it twice a day. very annoying.
Battery settings shows me that Android System is using a lot of battery.
2 days ago I did a factory reset and cleared cache but nothing has changed.
Someone has the same issue?

Sudden battery life drain

Recently my battery life has dropped extremely low. I have been running setcpu to underclock when not in use to preserve battery life and it was working very well draining 1% on standby every 2 hours approx. A couple days ago I had it on standby and somehow in the morning the battery was completely dead after I had fully charged it the night before. It is such a drastic drop and I didn't even change anything that I think it's the actual battery itself. I can watch the %'s drop just watching my phone now. Has anyone else had a problem with this? It seems that the battery can't hold a charge anymore.
Looking at my phone right now, I had it off the charger for about 10 minutes after it fully charged and it's already down to 90%.
The first question that comes to mind is have you made any changes lately? Installed new software? upgraded something? If your phone was getting okay battery life last week and now it's not, it's time to start pin pointing what, if anything, has changed. Keep it mind it is possible for a battery to die...
Someone on this forum told me to erase the battery stats. I was told to go into the recovery. I use clockwork. There is an option to reset battery stats. This worked for me but do some research on this site. I am not an expert but was told to do this by someone who is

[Q] Couple of questions regarding battery

Hi guys I know battery issues are covered a lot but this is slightly different.
The past couple days my battery has drained a lot. Within 6 hours usually its a minimum 7 hours until it reaches 20%.
But since yesterday Android System has been partial wake lock, according to battery use it was 50%. It was only till I rebooted earlier this afternoon that it was cleared but saying that the drain after a full charge ive been on battery for 3 and half hours im already on 53%. Should I use battery calibration app to remove battery stats? Im not sure if I should as once I reach 90% the battery stats reset itself.
Im on stock rom rooted latest firmware.
Thanks in advance

[Q] Gnex GSM: Do I have a phone or battery fault?

I bought my Gnex from Handtec at the end of November. I have been very happy with it Until 2 weeks ago. Battery life has not been great but has lasted 16+ hours each day and I always charge overnight so this has not been a problem to me.
I take phone off charge at 7am. A couple of weeks ago I started to notice that instead of 50% at 7pm it was showing only 20 to 30% charge.
I bought BetterBatteryStats which showed no WaveLocks.
I started to freeze apps using Titanium Backup.
The battery life did not improve. I noticed the phone was getting noticeably hot to the side of the camera and charges were taking much longer. Instead of 3 hours it was taking longer than 7 hours.
Last weekend I noticed a drop of 70% in 3 hours on 2 occasions.
So I decided to wipe the phone and install AOKP build 15 with Franco kernel 10. I did not re-install aps. I charged he phone after install which took all night and then reset the battery stats.
The phone has continued to be hot and discharge very quickly. Charging is very slow. If the phone is off - charging appears to be even slower or not take place at all.
My Gnex is now fully discharging in less than 5 hours when idle in flight mode and is always very warm without any use.
I have been using a Samsung galaxy s2 wall charger.
Is this likely to be a faulty battery or phone hardware fault.
Any suggestions for next steps or is it a Samsung repair job.
Thanks

well, whichever it is, it sounds like a hardware problem that should be warrantied. i would flash it to stock and get it repaired by samsung, or see if the place you bought it will take it back
I get a similar problem but i return it back to vodafone 2 days ago and now waiting for the results, i returned it a week ago and they only give me a new battery to see if that will solved the problem but nope it persist, now they too it for either repair or replace ....

I am on the same build and recently used francos kernel. At night the phone would drop 20-30% of battery on airplane mode. Installed the apex build 5 kernel and all the battery nonsense stopped straight away. It seems to be a great kernel especially with AOKP B15.
Hope that helps.

[Q] Battery life last couple days

My Moto 360 has been dying in about 4-6 hours the last 3-4 days. It appears to be around the time that recent update was pushed that rebooted my watch. Anyone else experince worse battery life since the update?
Mine has been slightly worse. I use to end the day with about 50% remaining.. Lately, it has been in the 30% range.
My battery was full when I left for work at 9:35am it is 1:33pm and it's at 22%...
I actually came to seek help for this same reason. Up til yesterday (maybe two days ago) my battery has been lasting roughly 16 hrs. Now I'm losing just over 10% per hour. Has anyone found a solution?
Add me to this list. Glad to know it's not just me, but it still sucks. Also noticing 8 - 10% drain per hour (per Wear Battery Stats). I've reset the watch, cleared out Play Services cache, uninstalled all other watchfaces, etc. Still the same drain, which seems to have started with the last update.
I know it makes a big difference regardless, but I turned off Bluetooth on my phone to see if the drain continued on my watch without it being connected. It stopped. In a hour I only lost about 3 percent. Could it be that after the update it is trying to sync too frequently or something to that effect?
I got the 5.0.1 update last night. I removed my watch from the charging dock this morning at 6 am and it is at 31% now at 1045 am. It is horrible. Wasn't this update supposed to be dramatically improving battery life instead of dramatically reducing it?
I had really good battery life before the update easily lasting through the day.
I hope there is a quick fix going to be issued shortly.
I hope the chaps at google are reading this thread.

So I had the same problem but I did a factory reset on the watch because someone in these forums told me to and now my battery life is pretty descent. About 12 - 16 hrs.
Can confirm, after updating to 5.0.1 battery life lasts like 2-3 hours... and its pretty laggy.
Motorola = fail !!!
I also have the same battery drain. After a 8 - 10 I use to have 60 - 50 %left now it is 10%. No new apps added. will try reset
Could it have something to do with the 1.0.5 Android Wear update? I was getting great battery life from 5am to 11pm, at around 30% left. Yesterday I was installing a new band and noticed it was at 15% around 6pm and then died about an hour after. Today I took it off the charger at around 5am and it's at 66% at 8:36am. This is ridiculous! I'm still on 4.4w.2 by the way.
Add me to this list, did the update this morning normally on about 60% now instead I'm on 11%.

So I don't know if something changed overnight, but I put my watch on a little over an hour ago and it's only loss 5%.
Update to my post from earlier. Was 66% at 8:36am and it just died at 10:30am. So, it's only been used for a little over 5 hours.
Are you guys using Facer by any chance? I ask cause I went from using Facer to using a stock face (Digital) and my battery life has improved drastically. I've now had my watch on for 2.5 hrs after a full charge and my battery is still at 91%.
I dont know if this will help or not......i also had the issue when i first updated the 360..........someone posted that a factory reset may work....
so i reset it....didn't quite help.....after 10 minutes or so...i noticed that the watch was quite hot...........i left it for about 10 extra mins and reboot the 360 again........after that....the battery life seems better......over the last 2 hours....i only lost about 7% of the battery......

I'm using Facer. I was just reading on Reddit that it could be because of the Facer update. Apparently the faces are using bits from 5.0. But, if you're on 4.4, the 5.0 faces cause the drain. Atleast that's what I was reading. I'm at work and don't have a charger. So, testing will have to be later.
I'm in the same boat EXCEPT I'm still on 4.4, not lollipop. However I do have the new version of wear.
Watchface gets HOT. I did a factory reset but battery life is dropping like a rock.
This happened to me once before, about 4 weeks ago. I solved it by doing a factory reset on my phone also.
are you guys all running battery wear status and other apps? i took my watch off at 8a this morning and at 12:35p i'm at 82%. i think that's probably higher than the normal 3.5% drain i'm used to seeing.
one thing I DID notice was that i ran the update with 100% and by the time i was done with shower, etc., it was already down to 87%, so i stuck it back on the charger.
Just an update. I went back to using a facer watch face. In 10 minutes my batter dropped 2%. Went back to stock face and a hour later it's only dropped 4%.
