Hi guys, I have my phone a few days now but usually let it charge over night when iam asleep so when i wake up, i just unplug and off i go. But last night the battery was still on 30% so i figured i would wait until today and charge it! I had read it takes a hell of a long time to charge but surprisingly my phone went from 4% to 89% in just under 2 hours! A few minutes later i noticed the led had turned green so i was like "what the hell, no way can it be fully charged that fast" ....... and it wasnt ha it was now on 94% so i have no idea why the led changed to green but it had gone from 4% - 94% pretty fast so i was happy and expected the last 6% to charge pretty quickly . The next time i checked my phone 2h35mins had passed and it was now on 99% but then it just seemed to come to a halt. I would check the phone every 5 mins expecting it had reached 100% but nope. Over 3 hours had passed before it finally hit 100% but the icon beside it read 'still charging' so i decided to leave it until it was fully charged . Well its now 3 hours and 30mins and the phone apparently is still charging lol
How is it possible for it to charge so fast up until it reached over 90% and then slow down DRAMATICALLY ? Is this normal? plus why the hell did the led turn green long before the battery was fully charged?
Always the last 10% takes almost 20 mins to charger whereas 0-90% can charge in an hour or an hour and ten mins.

20 minutes??? Mate it took almost an hour just to go from 99% to 100 lol Whilst on 100 for almost an hour it was still allegedly charging so whilst waiting for it to be fully charged i just lost patience and unplugged it as it was on 100 so figured it must be fully charged even though it was still charging! So in total the phone was plugged in for almost 4 hours and was still charging at 100% when i unplugged it yet it had gone from 4% to 94% in barely over 2 hours lol

That is kinda strange bro. Y don't u calibrate your battery by downloading an app from the play store or let your battery drain to 0% and shut down and then charge from 0-100 and check the time.

Good idea man,might leave it drain completely and see how long it takes to reach full charge! I suspect it should take a long time but it was just weird how not only did the led turn green before it was fully charged but it had charged damn fast up until that point and then just slowed down massively although its not a huge concern as the battery life is fairly good

I cannot understand why my phone shows battery full when it reaches 96%.
I also tried with a wipe with no results.
Ideas?

I must be blind... I'll have a look for the third time
Thx
from what i've read it does that to preserve your batery. if the baterry is charged to 100% and then discharges to 0%, doing that will affect your baterry life so by not charging to 100% your batery is going to last longer.

[BUG] Full Charge Oddity, Charge to 100%, Unplug to 97%
Same issue Reported on March 7th by me
kenvan19 said:
I'm having some even more strange battery performance. So over the past couple days my phone has charged to 97% then stopped charging. By that, I don't mean that it started discharging but rather it stopped showing any indication of charging and stayed at 97%. To try and see what was going on I decided to "calibrate" my battery. I absolutely killed it yesterday and plugged it in over night. This morning when I woke up, it was at the usual 97% so I unplugged and replugged it back in. I left it for a few hours and came back and booted it up to find it was at 98%. Odd because it charged from 30% to 97% the other night in 2.5 hours. So I powered it off again and checked back another few hours later. This time it had dropped to 97%. What the hell is going on here. I've decided to forego the calibrating and just see what the hell happens when I leave it on and plugged in. Its currently back at 98%
According to battery graph it did hit 100% about 2 hours ago for about 10 minutes then dropped back down to 98%. I'm completely baffled here...
So it hit 99% and stopped charging. Again, its not just saying fully charged, it actually is acting as though it is unplugged yet not discharging battery...Roger please help lol

Guys,
Was just wondering. how long is the battery taking to charge.. from the DHD, Iphone4, HD2.. they would pop to 100 within a couple of hours or so.. (NORMAL!!!)
This sensation... from 31% to 83% in 2.5 hours.. this is longer than i thought...
Mine took a whole 3 hours to go from 9% to 100%

I had similar problem yesterday. It sticked with %89 then I unpluged the charger and rebooted the phone. This time it says %100. Looks like there is a problem with calculation of percentage.
Yeah...mine takes a really long time to charge. I know lithium ion batteries charge slowly after it reaches 80%, but it still seems a lot slower than my previous phone.
yeah.. i rebooted and it was up to 99%.. strange. although it drained very quickly back to 87%... since been 3 hours and its not down to 77%.. so i think it is settling.. maybe an update
Desparately awaiting the root so all these irritating bugs can be addressed
mine took 4 hours yesterday....
Same puy my phone on charging in the afternoon at 10% and 3 hours later it was 75% which is not bad but still slower then usual
I plugged mine into a wall charger at 10 pm last night. At 6 am it was still showing charging and not full. Has to be a software bug. No way it can charge for 8+ hours and not be fully charged.

Normally 3 hour -4 tried to use another charger or cable
Sometimes it takes longer if you charge it with USB on some PCs USB ports.
Hello,
I bought this phone a month ago. At first the battery lasted quite well, I got around 5 hours of screen time with battery life to spare. Unfortunately, about 2 weeks ago I accidentally left the phone under my pillow and fell asleep on it- causing it to overheat a tad bit (I woke up 3 hours later and it was very warm to the touch and had turned off). After charging it up, I continued to use it normally but noticed that the battery would drain a little bit quicker than normal. Before I could easily go around 10 hours with heavy use and have 40% battery left, now after 10 hours it's left with about 15-20%. I am a heavy user but I haven't properly checked how much screen time I'm getting now, however I'll update that later.
As for the main problem- last night I charged my phone before sleeping (100%) and when I woke up in the morning it was turned off. I turned it on only to see that my battery had drained to 0% while on standby all night- whereas overnight I usually only lose around 2-3% battery.
After charging my phone up for 15 minutes- the battery level again returned to 100%. I only charge my phone through my laptop via USB. What happened here? Is my battery deteriorating? Should I get the phone replaced? I would appreciate any input on the matter. Thanks.
Also I've attached the screenshots showing how my battery died and how it was quickly restored. Can someone explain this occurrence?

Your sudden battery drop has nothing to do with what happened before.
Several people already mentioned this sudden battery drop as you can read in this thread, http://forum.xda-developers.com/showthread.php?t=2545553 and http://forum.xda-developers.com/showthread.php?t=2678909
No reason to return your device, its a know issue.
Drain your battery completly then charge your phone to 100%, turn the phone one and leave it to charge a hour more. Essentialy you have to recalibrate your battery.
So a brief update regarding SOT.
I left home with 90% charge this morning. Used the phone for 8 hours and it went down to 20% - granted, with heavy use.
Got 4.5 hours of SOT. Is this about average? imo I feel like this falls a bit below average. Ill check other threads as well and compare, but as far as I know, I feel like I should be getting a *little* more juice out of my phone. Data connection was on throughout, and some games were played and pictures taken.
Anyone else feel like they're getting sub-par use out of their battery?
*screenshots provided.
- checked the other threads, looks like ~5 hrs SOT is the most this phone puts out?
Same here.
Are there any news from Motorola?

I got a new Z5 yesterday and since then I've been playing around with it and I'm happy so far. Only issue is the battery level doesn't fully charge to 100 after an extended period of charging. Mostly it gets stuck at 97 or 98. I managed to make it reach 100 by turning it off and charging it while it was powered off. Is this normal? I've read that it's some sort of protection from overcharging. Really strange way to do it, though.
I charge mine overnight and it's always been on 100 in the morning
Are you using the supplied charger ?
Mine seems to take an age to go from 97% upwards... upto that point its as you expect, but like above i charge mine overnight and its always 100% in the morning...

yeah I am. guess this is what I need to do. I was waiting for it to climb to 100 so that might have made the time seem longer
I think from my limited experience it does seem to take longer to charge that last 5%, last night it ran out after about 10min it was up to 12% this morning because it ran out last night i charged it up before i came to work and seemed to take an age to go from 97% to 100% talking 15min plus... edit just to add i didn't use the sony charger this morning i used a charging station we have in the kitchen so that might have something to do with it also...

Yeah you are right the last 3-5% are long to charge
Tip. Never go down 15-20% it is better to keep your battery life

This is not a complaint or a problem requiring fixing, but some curiosity. Does anyone else's phone lie about how long till full? Last night it said 10 minutes till full at 96%. I looked away for maybe 2 minutes and it was 100% charged. I thought maybe the battery could need to be drained and recalibrated but no, it drained normally. Took like 5-10 minutes of facebook scrolling to go down maybe 1%. Used it down to 35% today at work listening to spotify and playing games on my breaks. This was probably 96%-35% over almost 10 hours, so I don't think I have a battery problem, it just does not display eta of the charge correctly?
The reasoning behind all this is I'm trying to practice good Li-Ion health and not charge it fully. I usually get it to around 95% and unplug it. I don't charge it all night, and give it a boost on the way into work in the car. Im using the PD 2.0 fast charger it came with at home, but a older Samsung fast charger in the car from the S8 era.
Trust the shown percentage and not the time remaining ?
