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.
So it's already been established that after the EVO charges fully to 100% it then stops receiving a charge and runs off the battery before charge cycling again. All the while displaying 100%.
Has any effort been put into changing the way this operates? Seems like it'd be nice to leave the phone on a charger and when you take it off, it would actually be at 100% and not at some arbitrary percentage between 90% and 100%.
It's better for the battery life.It's really good option if you ask me.

You mean make it so that the battery's status bar shows a realistic value once it stops taking a charge, even though it's still plugged in, right? Not actually changing the way it takes a charge. I'd be interested in seeing that happen.
Is that why when you unplug it, the first 5% or so disappear within minutes?

Yup. This is why when you charge overnight the battery plummets right after.

Don't leave it plugged it after it reaches 100%. Problem solved.

Valid point. Lol
There are some people who don't want to wake up in the middle of the night to unplug their phone. Like me.
annoying, but just unplug your phone when you do wake and plug it back in after about 10 seconds. let it finish fully charging while you get ready.
it's better for the battery though, case closed. Lenovo has been doing somehting similar w/ their laptops for years. It never charges the battery past like 97%, and when it does reach the top it stops charging until it falls below like 92 then recharges. HTC needs to loook out for the battery they already have enough flak from all of us for the last few years w/ every touch device they have had. We want more life, and they are giving it to us, just wish they could figure something out like lenovo, let it go down to mayeb 94 then charge up again perhaps.
it really isn't true, mine dumps 10% or so off the charger regardless of if it has been on the charger all night or 2 seconds after it turns green.
So I've done the:
1 charge to green
2 unplug
3 turn off
4 charge while turned off.....to green again.
And here are my honest results.
Boom........phone has 20% left after 16.5 hrs of moderate use (calling time total 1 hrs talk total, surf /post 1 hour total, load up 5 apps from the market, listen to audio clips on the speaker phone for almost an hour straight, podcast this morning for 30 min...and other randomness)
And still have 20% left. Going since 6:30 a to 10:30 p...........approximately 16 hrs equals 80% so about 3.2 hrs left to use before dead.
THIS EQUALS APPROX 19.2 HOURS OF MODERATE USE BEFORE RECHARGE NEEDED.
eat it Apple 4G . You can't even reliablly make calls let alone last that long without charging. My 3g never lasted that long. You still need a wall Apple we are truly mobile. If I was on the road I could (don't need to just yet) swap out for another battery.
I'm loving xda for all their brains helping me get the most out of this phone. Thanks to all.

The point here is that we shouldn't have to do the "charger circle jerk" to have 100% battery. I should be able to unplug it and have a full battery. Not 90%. I might need that 10% later on today, its accomplishing nothing sitting on my nightstand.
If the battery is toast after a year instead of a year and half, i don't care. I want a fully battery, not an almost full battery.

HTC advised a similar solution to the battery issue. I did this a few times and my battery lasted more than 15 hours with moderate use. Here's the post:

My phone used to do this, even after i followed all the little tips and tricks of playing hide and go seek with the charging cable and my phone.
Know how i solved it?
Bought one of those $10 Ebay 2 1500mAh TP2 Battery And Wall Charger bundles, now i dont use the OEM charger at all, the cable turned into a permanent USB cable on my comp and never sees the actual HTC charging unit it plugs into for AC power. I have 3 batteries and i rotate them in that little wall charger which actually charges them to 100%. Its also proven because if you take one of the batteries, put them in the phone and charge them until the green light comes on, supposedly to "100%" and then take the actual battery out and put it in the ebay wall charger, it will still charge for another 15-25 minutes. Charging it in the phone, as soon as i unplug, it almost instantly always drops to 90%... charging with the ebay wall charger, it will stay at 100% for a while before it falls off.
Below is the link to my thread which contains linkage, pics and info about the ebay bundle, others also claim the same issues and fixes in my thread. I mean for $10 bucks, does it really matter if it works for you or not? Its worth the shot and for me, it was a great investment.
Best of luck.

I did this last night and I'm at 14 hrs and 57% left. If I have to charge like this to get great battery life that's fine. My iPhone 3gs would last half a day. So this is blowing it out of the water. And I can hold it with my left hand to talk.

You can hold the 3gs with your left hand as well...

Good stuff man, I finally just switched batteries after 21 hours.
Hey Guys,
i got my ZL 3 or 4 weeks ago, and can say it´s absolutly awesome, but since ca. 2 weeks, i have a problem with my battery. The problem begun, as i found my battery completely discharged, so i put it on the charger. But it didn´t charge the whole night. In the next morning it startet to charge, i waited till 100% an took it off the charger. Over the day, i watched the battery drain, and it was more than normal, the battery went empty, after a 5 or 6 hours with 95% standby time. At home i charged the phone again up to 100%, ab pluged it off, the next morning, the battery had lost not a single percent off its charge. So i went to work, with the phone in my pocket. A little later the phone got really hot, i pulled it out and, found the battery with only ca. 55%, so i turned off the phone. 45 minutes later, i turned it on again, and the battery had only 27% left. And so it goes on the next days, with more or less battery drain, some days the battery holds 10 hours perfectly, and at some other days it only holds 4 hours and less. And now the charging procedure have problem too, when i charge the phone via USB, it charges unbelieveble slow, and even discharges sometims , but when i charge it with the power adapter, it charges unbelieveble fast, you can watch the percentage rise in minutes. I tried the STAMINA modus but, it didn´t help at all, and the screen is on the lowest brightness.
And i have too say, i don´t have any apps activ, and 3G is only on for a few seconds sometimes.
The phone isn´t rooted, or everything else, it´s completyly stock.
I hope someone experienced any similiar problem, and have a solution for me, because it´s an awesome phone and i didn´t want to miss it.
(Sorry for my not so good english)
Yours faithfully
Tim
Good morning.
I own a Samsung Galaxy Note 10.1 2014 edition for about a year now.
I sometimes had a problem with my tablet when charging, once I plugged it a red cross would appear on the battery icon, if I left the cross there the tablet would charge terribly slow, I would solve the problem by disconnecting and connecting until the cross was gone, so the tablet could recharge normally (which he did).
That was until yesterday when I put it to recharge and left it overnight, when i woke up i realized it had only charged 48%!! I left it for some hours more and when I went back to check it was still 48%. I turned it off and let it charge, which got me to 100% but when I took it to school after it reached like 40/50% it went instantly to 15% and then to 4%.
I then, when reached home, tried several chargers (all from samsung) and installed this program to check on the battery (battery monitor widget) and it showed me that the mA flow was unstable, from 90mA to 1400mA (while on my samsung S3 the flow was 999 al the time)
I tried all the chargers on my S3 also and they charged my phone from 13% to 100% in 30 minutes, so I think it is not my chargers fault.
Is battery dead?
I leave here three screenshots showing some battery data.
EDIT: I have bought one cover from ebay, that came from china, it has some magnets on the back, could the magnets be somehow related to my battery problem?
So I've been having the same issue. I do believe there is a connection with the cover. I had removed my cover to inspect the charging port. I couldn't see any damage so I turned on the tablet with the cover still off and plugged in the charger and it worked just fine. Now every time I have to charge I just pull it out of the case, pop the button lip around the port off and then back on back and like magic, it works normally for a period of time.

Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
