Hey what have you guys n' gals been getting off your XDA IIs for battery life. I am away from home just for one night this week, and have forgotten my charger (Must get a sync n charge...but where!!!!) I'm only using PDA functions and Duality Email....and battery is already at 83%
Will it last 48hrs!!!!! We'll wait and see!

Obviously using it as a PDA does use more battery life.
With my phone 'off' (well pda bit off) and WiFi off, over a 12 hour period of inactivity I'll use maybe 5% of battery, so when it comes to bed time your battery use will reduce.
if you're away from chargers I'd advise keeping wifi off, it's the battery eater portion of the functionality. a little light GPRSing shouldnt hurt if you need email, bluetooth isnt a big issue, but if you need to last 48hrs, dont touch the WiFi :twisted:
Also I have noticed that my battery goes from 100-95% REALLY quick (like 10 mins with only BT on), but then takes maybe 30 minutes of wifi browsing to use a similar 5% in the 50% range!?!? non-linear battery consumption maybe? Might be just mine.

I've noticed the same but, conversely, when charging, it takes longer to charge the last five percent than the rest. So, I put it down to the Battery monitor API. These things are never 100% accurate.
As for battery life, two days from normal useage and three and a bit days if I'm careful. I have no problems going for a long weekend and not taking the charger as long as I have no plans to use it intensively.
I find reading an ebook with mobipocket also kills the battery at about 10% for every hour and nearly treble that if I'm listening to music at the same time.
1 Day, its usually down to < 30% come time to goto bed. But then, it gets well used.
So, the question has to be asked..... Who has the charger by the bed?
/me raises hand.
Sync cradle is at work... which charges too.

Battery Life on XDA
If you turn ON flight mode you will find battery life will improve but you will not receive "always on emails".I've got a feeling the phone wont work either (i don't use mine as a phone so not sure).I know when you turn flight mode off again you will have to enter PIN no.
I used this method when I was in hospital for a night and they would not let me charge my XDA.
yeah : flight mode = turning off the phone part
I have a brodit cradle in the car , charges it extra while commuting
As default when you get the phone, it will ask for a pin number. This can be disabled though through the software!
Flight mode will of course save battery - like said - its not using the phone functions which are probably the most battery draining.
I have to use my charger twice a day but i do cain it as my job is so ****ing boring! i hope to god someone invents a....
Solar panel charger
so i can go campin in wales on ma scooter and not need to sneak my phone into the pubs wall plugs all the time
I have a brand new M2000.
I took it off charge at 08:00 this morning.
I got to work at 09:30 and started using it.
I had bluetooth on with headset and I was using wifi on and off.
I started getting low battery warnings at 15:00.
That is very poor
I have BT on and can run from Thursday night through till Sunday without a problem. Though I do get worried about making calls on the Sunday. If anyone has a description of how to convert an XDA car cable to XDAIIs I would be gratefull.
I feel like my battery life drops fast unless its just cause its going down in 1's but what methods are generally used to conserve battery life? I just got it so right now im doing a test to see how long it'll generally last throughout the day I think i had it unplugged since.....10am and its 5pm and its at 61% is that generally normal? again thats an estimate when i unplugged it.
To decrease battery wear the TP2 will not continuously charge the battery while plugged in. It will charge the battery to 100% and then let it drain till you plug it in again.

This has been discussed several times here, a search will give you much more detail, but in general, turn off WI-FI and Bluetooth when you are not using them and turn off 3G unless you are using data.
Gordon
Check out on the applications too that you have installed. At least I had one application which I cant still figure out the need for it to run in the background, but it did. Once after un-installing the battery is really great.
Disable 3G and WIFI when not needed.

Maybe your charging problem
When charging , you must power off until 100%
And maybe your charger cable have problem .
And also you try this kernel

I'm new here since I bought the device yesterday, but this looks like a general issue...
This thread explains battery saving, some issues that might be related to your case are:
- If you misuse Greenify or any other "battery saving" apps they can actually lead to battery drain
- @gafri1: If "When charging , you must power off until 100%" means that every time you charge you must do it until 100% then it's false. Lithium ion batteries DO NOT have "memory", so charging to 100% or 70% doesn't make any difference. There's this thread that contains a brief explanation and this entire website dedicated to batteries.
As far as your specific problem is concerned, what do your battery stats say?
Better Battery Stats and Wakelock Detector can be used to collect more complete battery stats. They DO NOT SAVE BATTERY, they just tell you what might be draining it. The first step should be to check the built in battery stats in the Settings and then turn to other more sophisticated tools.
Charging issues
OK, had a few instances of odd charging that may be what is happening.
One OEM cable got pinched at the head of the micro USB. Shorting and bad connection. Battery shows charging, but never increasing charge.
Ended up melting the head and heating up the tablet.
Long aftermarket charging cable or extension cord. Some do not have proper pin out... will not charge or show charge. End up having little charge after disconnecting from charger.
I watched, a tablet go from 100% to 90% within 2 minutes and slowly decrease the rate until it leveled at 60%. A false reading of charge state until battery data caught up with battery's true charge.
WiFi only, or connected to cell network? This is a very important detail, since if its on the cell network, the reception in your area can have a HUGE effect on battery drain. In fact, when talking about smartphones, I'd say cell reception is the primary factor behind battery life.
In any case, the battery drain you mention (30-40% drain with 1 hour screen on time) is not awful, although not great either. Especially depending on what you are doing during that screen on time (gaming can be a huge drain, streaming video too, but usually less so). I get maybe 5 hours screen on time if I'm watching Netflix. That with no battery saving, WiFi only Note 8.
Also, make sure Smart Stay is turned off, as it seemed to me to be a big battery drain (and never really worked all that well for me, anyway).

Agree with both these points. I've seen these "battery saver" types of apps (Juice Defender in particular) which have caused more issues than they solve. Some folks will swear by them. But don't take for granted they will increase your battery, and use them wisely. Don't "misuse" them as you say.
And charging while the phone is powered off is a myth that has been debunked long ago. Aside from the fact that the device will charge slightly faster (it won't be draining as its charging) this will have no effect on battery life.
Thx for information
exactly the same for me
I posted it here:
http://forum.xda-developers.com/showthread.php?p=50558312
Sorry , Thx for the info , my note sometimes when charging until above 80% can go up until 100% in one minute what's about this problem anyone know ?
(Sorry bad English)
how many hours did you charge your note 8?
When i use new cable (custom cable ) the charge became faster , i only charge 2 hours 30 minutes
Become 100% , is it problem for my battery?

I have noticed some cables are faster than others. My bedroom charger will charge from dead in under 3 hours, the downstairs one will take 4 hours.
leave it on power saving mode always. It's the only way I get the battery to last on idle. in comparison the ipad air can sit days / weeks almost on idle.
Does battery lfie improve with CM? Can we put CM on 4.4 kitkat note 8?
Reading through some battery threads I was told that the "proper" way to check your overnight drain was to charge up to 100% and not touch it until the next morning. I tried this last night and WiFi drain was in the 30% range (I used my phone before taking the screenshot which is why it's at 22%) with a total drop of 7% (100-93% over 8 hours).
Does this seem high?
I've got WiFi, NFC, battery saver location, mobile data, and double tap to wake on. The phone is rooted and I'm using a custom kernel (but I'm pretty sure it happened with the stock kernel too). I also have an Android Wear watch attached all night. On AOSP ROMs on my OP3T overnight drain was around 2% if I started at 100% and WiFi was never more than maybe 6% of total drain. Again, I'm not asking how to fix this, I'm just wondering if this is something that others are experiencing.
Thanks!
Mine dropped 2% over four hours of sleep. I'll try with battery saver on.
Mine averages about 3% in 8hrs with wifi on, I'll post a screenshot tomorrow, on freedomos using simplegx kernel
My WiFi drain is very low during idle. Like most flagships of this era.
mine is as same as op, but last night i charged it upto 74 and slept and when i got up after 6 hrs or so it dropped 2 %, strange ... maybe it's the way the phone is charged and calibrated for dash charging
I'm loosing 4-5% in 8 hours.

Thanks for these screenshots. Obviously I don't have nearly the SOT that you do in my screenshot, but it looks like if our SOTs were the same you'd probably have similar WiFi percent usage.
Mine's been surprisingly bad - at least, worse than my Moto G5S, Galaxy S8+ or iPhone 8 Plus were. I'm losing like 5-7% every four hours, my battery drain while connected to wifi at work is way worse than either of the other phones mentioned too.
All in all it's kind of disappointing considering how good the OP5T is in literally every other regard.

We may have similar WiFi usage. But my drain is about .5% per hour, overnight. I don't consider that high, and battery consumption has to be attributed to something. Here is my current usage since yesterday's charge.
On 8.0 the WiFi drain % is even lower, but idle drain per hour is the same. So it doesn't really matter.
Very bad.. Battery go. Down quickly in night..
My wifi drain is also really bad on the latest 4.7.4
Hope they release a fix soon...
Edit... I did a fresh install with stock 4.7.4 and it isn't as bad but still is present. At least it's more tolerable.
Sent from my ONEPLUS A5010 using Tapatalk
So I did another test last night (4.7.4 and SimpleGX kernel) and had 3% drain. With all the comments here I think the high percentage of WiFi is normal and probably not affecting battery life a lot. I am starting to think the kernel may be providing better results than stock 4.7.4 though since a lot of people are mentioning poor battery on 4.7.4.
I don't even know how long, all I can say is my battery drains 3% every 9 and a half hours. Both bluetooth and wifi was on. This is on the stock rom and kernal, not sure how you guys have such high battery drain... Are you guys sure it isn't another app hijacking your battery? Because from my experience the battery stats isn't always perfect. Sometimes I was told that it was my screen (on my old phone) in which it was actually a 3rd party app. After removing the app, my battery drain went a lot slower than usual.
Has anyone tried this toggle in Developer options?

Just tried that setting last night and it doesn't make much difference.
For all wondering I have an Android Wear device connected 24/7 and location set to battery saving. I also keep NFC and data on all night. I'm not using screen-off gestures though.
I wish it was only 7% or something like that on my OP5T.
I used to be one of you 3%-battery-"drain"-at-night-guys, until the official update to Oreo. Now it uses 36% in 6h38m, of which WiFi is reported being 29% (1044mah, despite 0m active and background usage reported). There is 2.8MB additional use according to the WiFi data usage report that was set to count from today, yet the numbers per app have decreased, so there goes reliability on that. I haven't added or removed any apps, only wiped cache after the update. On standby, it only takes 18 hours for it to drain, which used to be several days.
Another weird thing is that WiFi is terribly slow since the same update, but only on this device. (No numbers yet)
Right now my plan is to test all the mentioned related settings, as well as WiFi off, make screenshots after each nightly test, and finally do a complete wipe and perform the same tests with a minimum of apps, and then redo them again with my usual set of apps. It could still be one or more apps that misbehave on Oreo specifically I suppose, so if there's any indication for that, I will start eliminating apps one by one until I find the culprit.
I've a brand new Xiaomi Mi 10T Lite, but since a few days I notice that it seems that the battery is draining fast.
So I've done a test: I've charged my phone to 100% and used it until it turned off due to too low battery and it lasted 23 hours and 3 minutes.
But I doubt if this is normal and I'm kinda worried about it.
I've bluetooth off, and wifi is always on except when I go outside and then I use mobile data.
I use my phone for surfing, using social media, chatting, gaming, making nice pics and more.
So is the battery life normal or is this a serious problem?
is 23hr bad ? I feel like my one is always above 80% as it charges that fast I don't seem to notice the battery being low

I dunno
I haven't mentioned the standby time and the active time in the topic, and I cannot find that data anymore so that means I have to do the test again
I would advise to install AccuBattery app, fully charge the phone and look at screen off and screen on power consumption at the end of the day.
These numbers are "normal":
Screen off - no activity (over night or phone just laying down for a few hours): 0.2-0.3%/h
Screen off - the usual daily activity (moving around with the phone in the pocket, Whatsapp for web active, Google location tracking active etc.): up to 1.3%/h
Screen on - about 7-9%/h
I'll do another test on Friday as I said.
I'll charge the phone to 100% and use it until the phone turns itself off due to low battery and look at the active time then.
I'll post the results here if the test is done.
What were the results?

My phone is pretty new and I am using it more frequently these days. This leads to similar battery times like you describe them.
I did not do the exact same discharging like you did, but imo battery drains mainly during screen-on time. Over night it is quite stable and only slowly discharging.
Maybe power consumption is dominated by the LED screen? This might be the reason why Xiaomi has such an aggressive screen dimming implemented...
I think what _mysiak_ is describing above, is pretty accurate and explains what you are observing.

Unless your trying to calibrate the battery that's really stressful to the battery to use it like that.
Puts a lot of wear on it... fast.
