Anyone having an issue with their phone only charging to 98%? It will only each 100% if I unplug it for a bit once it reaches 98% and then plug it back in.

not seeing that on mine.
It does this by design. It prevents battery damage and prolongs battery life (in terms of life expectancy and usability over years).

I've had the 98% issue since day 1. I've never seen 100%. It appears to be a very rare issue. Otherwise my battery performance is great!

that happened top me on my first charge
just give it a couple charges it will start going to 100
I have to say battery life is great for me on pixel 2 xl. every time i charge it will go all the way to 100 %.
Hmm, I've charged it overnight for awhile now and it still won't get to 100%. It'll say that it's fully charged but will just show 98%
Experienced the same thing on my Pixel 2 XL. I did manage to fix it by powering the phone off for 10mins with it plugged in/charging. Once rebooted it showed 100%. Otherwise it will stay at 98 or 99% forever...
Strange thing happened yesterday. It finally charged to 100% and 5 minutes later I unlock the phone and its back down to 99% while still plugged in to the OEM wall charger (showing charging rapidly).
Copy and paste from my post in the Real Life Review section:
I would leave my 2 XL charging overnight (stock charger and cable) and when I wake up around 7-8 hours later, the percentage would either be 97%, 98%, or 99%. I've rarely seen my phone go to 100% since getting it on the 18th.
Whenever the battery hits 50% and I go and charge it mid-day, it would take a painfully long time to charge up after around the 85% mark (the general consensus and expected). I would check and it would be at 99%. After around 10 minutes, I check again and it shows 98%.
Needless to say, I disabled "show battery percentage". If the battery icon is full, then it's 100% to me.
I have this with my 2 xl too. It'll stop at 98-99, and if I unplug/plug back in a few times or reboot a few times it'll eventually get to 100. But it'll drop from 100 only after a few minutes even unused. Not sure if by design or a minor hardware issue.
Mine was charging overnight to 100% now for the last 2 or 3 days it's only been going to 98% overnight. Battery life is still good though.
I was wondering of was something to do with Battery Stats, maybe needs cache cleared or resetting somehow.
Actually I cannot even get mine to charge to 100%

Actually I cannot get mine to charge to 100 percent except two charges ago. That being said there must be something wrong as using the white charger and cable to go from 2% - 98% it took more than 5 hours ! I cannot get it to go past 99 % and I have been charging with phone off then with on and then according to Google support tried safemode but still no difference. Highly frustrating for a $1k phone. I finally shut phone off for the last 20 minutes and then checked the charge and it is now at 100% but what a battle and a SLOW SLOW charging phone.
I never charge mine to 100%, I usually take it off the charger around 85%. Not had any battery problems, don't think it's ever necessary to hit 100%.
I've had the opposite. Wake up it's 100. Listen to music on the way to work for about an hour (bluetooth). When I get there it is still 100 percent. Put it in pocket for another hour, check phone, 96%.
I turned off my phone when plugging it in last night hoping to make this go away.
When I turned it back on this morning... still only 98%...

yes, mine started around a week ago (black 64GB) today as soon as i unplugged it dropped to 98% used it for a minute n it went to 95% sometimes the phone wont even charge to 100%

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.

Good stuff man, I finally just switched batteries after 21 hours.
I have now done three cycles now drained to 1% and put on charge over night when I unplug and check the phone it says 98% and drops 2-3% within 5 mins of use. But if I plug it back in it will then go back to 100%. Anyone else?

There have been threads about this already. Batteries, once charged fully, cannot 'keep charging', so they will stop charging until it is low enough to charge again.
This protects the battery from all sorts of nasty and evil things.
^ precisely. Batteries shouldn't be pegged at 100% and continue to be charged. The firmware lets it drain down then charge up again. You can just get 'unlucky' and unplug at a point where its discharging and at 98%.
I remember that happening with the Nexus S. I'm thinking it must be a Samsung thing. It's just one of those weird OEM things like, Motorola phones measuring the battery in 10% intervals.
All manufacturers charge their batteries this way but there are many ways to mask that process. People apparently want to see a fully charged phone when they plug it off the charger. They don't mind that their phone drops to something between 95% and 100% in a matter of minutes as long as it's "full" upon disconneting. Seems Google just displays the correct charge instead of pretending to be on 100%.

Pretty much. The G2 with stock firmware (and from what I remember with the Evo 4G w/ stock), HTC charges to 100%, discharges back to 90%, and charges back up again. etc.. The LED charge indicator turns green at 90% (so according to them, anything about 90% is a "full charge").
You can see this in regular use. There are days where my phone sits at 100% for hours, and others where it only takes an hour to tick down do 99%, even with the same usage. Just depends what "state" the battery is at when you pull it off charge in the morning.

Is there a preferred battery charging regimen for the One X battery?
That is, is it better to, say, always let it drop to 15% and then recharge to 100%, or can/should I charge whenever possible, or in smaller increments?
Also, are there disadvantages to using the phone while charging (as I tend to do quite a lot )?
Thanks!
i normally let mine down to about 10% then just charge it too 100%

Right, but do you know if this is actually the way to go with the Li-Po battery or are you, like me, just winging it?
When i first got my phone i let it run down till it asked for the charger, then left it on charge over night.
I did this for the first 3 or 4 times as i found this yields the longest battery life, since then i charge every 2 days regardless what percentage is left always over night though.
Going to leave it tonight & see if it will go till tomorrow night, its been off charge since 7am on Friday morning so far & is still on 46% a total of 39 hours so far.

You get two days on a charge? Are you a wizard? Although, having just got the phone (and possessing the patience of a 5 year old), I've done a lot of start-stop charging, which I suspect isn't optimal.
I'll try to refrain from trickle charging for a while, see how much difference it makes. Thanks.
Another battery charging thread? Just plug in the damn phone! It will take care of the rest.

I have noticed that the battery does drain in strange amounts.
I have my wifi & gps on constantly, my phone went for 2 days 5 hours & i received a text at which point the phone was at 34% battery.
The phone was put back in stand by & the phone went totally flat in the next 4 hours, this i find strange as over night in stand by it only uses 1 - 2%.
There is obviously a bug in the way the phone reports its battery state, by my reasoning this must be some 10 - 15% lower than what it is reporting.
It does seem to have some difficulties reading the battery level correctly. I've noted a couple of times that it shows a significantly higher charge level (+5-7%) after a reboot. Which is hardly likely to recharge the battery. (Unless I got me one of those perpetuum mobile, in which case, yay!)
Something odd happened to me today.
I went to sleep listening to an audiobook, the G3 was at 100% battery.
When I woke up ~8 hours later the battery was at 99%, it was plaing audio the whole time.
Obviously a display bug, when I went to see battery status it said 648 hours left.
So I restarted the G3 and nothing changed, the battery is now at a lower % but it behaves as though nothing happened.
Please tell me the battery micro-controller isn't screwed and doesn't now report 70% as the new 100%.

I had something like this as well, but it went down a tick eventually. i was browsing reddit for 30 minutes at 100%, then it went to 99%. Not sure if it's just amazing battery life, or somethin'gs up.

I would drain it to 0% and then charge it to 100% without unplugging it. That should recalibrate the battery
From 100% > 99% seems to take an age. But soon as it hits 99% it does drain considerably faster.
If you check you batter after you have charged it, it always says Estimated time remaining and collecting battery info... please wait.. until it drops to 100%
I have same issue but its not bother me much. Whats bother me is that some times when I go to sleep and live phone at 60% I wake up tomorow and its 60% and sometimes drops like 3 or 5%...any one have that issue?

Well, it's hard to say but maybe it wasn't a problem after all.
Seems like the battery % is highly inaccurate at top levels. 100->99 takes much longer than 99->98.
I took the advice of someone in this thread and fully discharged the battery and then fully charged it.
It did take a while though, 6-7 hours from <1% to 100%. Using a computer USB port for charging.
Is charging faster with the provided power USB adapter? Or with wireless charging?

Yes and yes, if you use an apropiate AC Adaptor. Pc is usually charging at 500 mA and an Ac Adaptor up to 2 Amps. So you charge 4 times quicker in theory.

Custom rom has nothing to do with it. I am running the stock version, and my battery won't charge up more than 64% right now. It seems the problem starts with 96/94% but gets progressively worse. Sometimes it will fix it self for a short time when I replug, but right now even that doesn't work for me.
I checked last night, and I believe the kernel just thinks the battery is nearing it's 100% state. This was a screenshot I took that shows that the battery isn't charging at full power. The closer I got to 64%, the slower the charge went:

Have you tried just using the tablet when it was "fully" charged to 64%? I see three possibilities and I would be curious to know was the case:
1) Your battery is only charging to 64% and when you start using it, it will decrease at a normal rate and you'll get 1/3 less time out of the charge.
2) Your battery is showing 64% for all charges >= 64%. So, it could be at 100% charged and will stay at 64% until you've used up 36% of your battery.
3) It is scaling wrong so that 64% == 100% and the battery percentage will decrease as you use the tablet, but it will decrease 1/3 slower than it used to (aka the time from 100% to 0% when you first bought it would be the same as your time now from 64% to 0%).
Any idea which of those three is actually happening?

Definitely the first one. Right now I am at about 35% and have 2.5-3 hours screen time since the 64% (can't check for a definitive screentime as the indicator doesn't reset unless you charge to 100%). So that would translate to the about 7.5-8 hours I get when I do have a full charge.
I also checked once before when I had this issue by letting my battery completely discharge and then start up my tablet again and I had 1% left, so it was pretty much completely drained. I'll probably charge it again tonight and I expect I will have an even lower full battery percentage.
Try using a different 2amp charger and/or different cable

The only real fix for this opening the back up and unplugging the battery. When you plug it back in you won't see the problem again. Not sure why.... But that's how I fixed mine. Been good for two months now.

Also tried that already. Still only charges up to a lower percentage. Only thing I haven't tried is unplugging the entire battery.
It charged up to 100% for some reason last night. The only thing that is really weird that it charged 1% every five minutes from like 85-95% and then suddenly in the last 5 minutes it instantly charged from 95 to 100%. The whole battery thing is just really weird.
