I got my Tilt 2 yesterday. I charged it to 100% before using it, then had it on all afternoon setting it up and adding programs. I charged it all night, but when I got up this morning the battery said 70%.
I went to the power settings and noticed there's an information tab that has status info since the last full charge. The status under Last full charge on my phone said "not applicable". I plugged it in at work this morning and waited a while to make sure the charging light turned from orange to green. It did and the battery power remaining was 100%. I left it charging another hour.
A little later I checked the information tab again. It still says Last full charge: Not applicable. HUH???
Aside from the Last full charge field, it also has stats for Standby time, Talk time and Device usage since last full charge. Since I apparently still haven't had a "last full charge" all the values are 0 on my phone.
Does anyone else have a date and time in that field on the information tab?
i got the same on my imagio.
When I first got my Tilt 2, I noticed that screen and thought "hey that's useful". It had the values all filled in properly. But when I went back later to check it, I saw "Not Applicable" just like you. It seems to be intermittent though, because I checked it just now and it has good data. I haven't noticed any correlated factors that predict whether the info will be there or not.

you should never leave your phone plugged into the charger after it has reached full capacity. you're basically draining the overall battery life of the phone, so it won't last as long off of a full charge.
did that to my old tilt before I found out about the overcharging thing, and had to use my warranty to get a new one since the phone would shut off by itself at 90%+ and turn back on again with >5% battery power left

I wasn't really sure that it was fully charged because of that stupid message about the last full charge not applicable. Thanks for the information. I didn't know that it was possible to ruin a battery by overcharging it.
@enisoc,
I thought it seemed like it would be a useful feature, too. Every single time I check power settings the values are null. It's interesting to know you've seen data there at least twice.
ETA: Now that I think about it, for the last two years I've plugged in my Tilt before going to bed and left it charging all night. Every morning it was 100% charged and I never noticed any adverse effects.

Maybe I've just been very lucky, but I have had a Sprint HTC Touch and before that a Samsung Blade (razr wannabe), each for two years. Every night for those four years, I plugged in my phone before going to bed and left it there. I have always had great battery life on both phones.
Specifically for the TP2, I have read that it stops charging at some point when it's done, and won't trickle even if you leave it plugged in. This has been reported by various people because they find that if they leave it plugged in for very long times, they'll end up with only about 95% battery, because after the first few hours it was no longer charging.
Perhaps less convincing, but also interesting, is the fact that (when it works) the "last full charge time" on my TP2 shows up as a couple hours after I went to bed, rather than the time when I unplugged it in the morning.
YMMV

oh wow really? that's interesting. that would be nice if it's really true. what I've been wanting is an app that allows the phone to make some sort of noise (i.e. an alarm sound) when it is fully charged. just to let it's owner know that it's finished and so it won't get overcharged. I think i'll go request it at development n hacking.
I am 100% sure that you cannot overcharge a TP2, in fact I would say any phone or device with a Lithium Polymer battery.
..........
it's true, once the TP2 hits 100% it stops charging the battery & the usage time will kick in.
Day 3 and still no data in the battery power information tab.
do a hard reset. mebbe itll work.
Since its very new, you got nothing to lose.
flip, do you have a TP2? If so, does that tab give you data all the time?
yes, its a Tmo TP2.
it worked on the Stock rom.
I have a custom rom now, and it works as well
once the green light comes on on the touch pro 2 u it stops charging, u cannot overrcharge it
Not only can you not overcharge the lithium Ion batteries it is actually better for them to be recharged as often as possible.
Menneisyys wrote a great article on it a while ago. This confirms what I have always been told.
http://forum.xda-developers.com/showthread.php?t=342162&highlight=battery+charging
Overcharging li-ion (and li-po) batteries results in catastrophic failure, a.k.a. explosion. Therefore, chargers for these battery chemistries stop charging when they're full.
Something is wrong with ne WM6.5 driver!
Yesterday my battery duration was about 24h (with 6.1 i charge it every 2-3 days!)!!
I fully charged at midnight and now, after 15h it says 90%... It's a little bit strange!
At midnight i could see battery stats.. Now it says "not applicable".
I used Dr SigStat and it says a temperature of 2,47°C!!! (in WM6.1 temperature was normal).
What's wrong??
Over the weekend I finally got some data on the information tab. Either Saturday or Sunday morning when I checked it gave some time around 5AM as the last full charge time. Now it's back to Not Applicable.
@D J Palmis,
I wonder if anyone knows the answer to the 6.5 battery dilemma. When I was using a cooked 6.5 ROM on my Tilt I was getting normal battery duration. My battery life on the Tilt 2 is comparable to my old Tilt.
i see this on my tilt2. battery info shows up, with idle/usage times for a short while after full charge (green) if i check after a few hours, it goes to n/a. looks like a driver bug to me.

No issues with battery here.
My advice would be to completely drain the battery.
Keep powering the device on until there is absolutely no juice left.
Then remove the battery, re-insert and leave to fully charge without powering the device on.
See if that resolves your issues.
Battery life on mine is excellent after a weeks useage, no complaints here.

Have you tried this yourself? Because, I wouldn't probably be comfortable draining the battery quite as empty as suggested by this method. The Li-Ion batteries need some charge to be left in them even when they are "completely" discharged, or else they are damaged (it may actually stop accepting charge, so recharging becomes impossible).
I think it should be enough to just leave the device on for as long time as possible - until the device finally shuts itself down. Then do a full recharge and you should be ready to go.
Of course if you've done this yourself and can confirm the battery still accepts charge after such procedure, then no serious damage has presumably been done. Wouldn't go quite this far myself, though.
Cheers
I can't say for certain about the TP2 battery but most Li-Ion batteries will have a tiny protection circuit in them to prevent over charging and over discharging. Becasue of the potentially explosive nature of Li-Ion batteries I would be very suprised if the TP2 battery didn't have any protection.
Yes that's true. And TP2 most certainly has this chip. However, I'm not 100 % sure if that chip can protect the battery against this kind of "abuse". It probably can, but I wouldn't like to be the first in line to check if it can or not...
I agree with what you all say, and yes I'm pretty sure that the protection circuits are there. I haven't tried it on my Rhodium, but did on my Raphael after lending to a colleague who was incapable of maintaining. Charge would hold for around three to four hours of useage, pretty damn useless after a week of abuse.
I totally disharged as much as I could, then left overnight with the device powered off and since then the battery useage has been as norm.
I know were not supposed to be affected by memory issues, but go figure...........

did as you said drained it right down even powering on again to make sure
gave it a full charge while powered off
from 5 this morning it has been in stand by and has about an hours use and im down to 2 bars on the main screen
when fully charged i check the power in setting and the last green bar was not lit
nothing running in the background
any other ides to try to sort it before i contact MPD and see about getting a new battery
thanks again for the help

Hi. I have a Voda branded TP2.
I have installed the 1% battery indicator and have realised that the battery is dropping at an alarming rate. In two hours without any data activity, just two calls of 5 mins each and the battery has already reached 74%. The number drops in front of my eyes. Quite scary actually.
Anybody else faced a similar porblem?
2 things I can advice you (as a TP2 beginner)
-First times: charge up to 12 hours non-stop even when light is green (has nothing to do with phone but with the chemical proces inyour battery) this will prolong lifetime
-This TP2 WWE ROM has a lot (and I mean A LOT!) of background running stuff compared to other WM 6.1 - ROMS. So you thing it is not using any current but it is!
Maybe you could install advance task manager and check out all running programs and processes ...
hope this helps ...
greetz,
Kjoere
Thanks. I have done the 12 hours charging many times - about 6-7 times. Will try the advanced task manager.
Anybody else with a battery problem?
Any application / software is known to be a battery drainer?
Thanks
Had a strange one last night. Went to be, put the phone on charge (was about 16% iirc), and the orange light came on to say it was charging. Then, this morning at about 3am, I hear the phone making bleeps. Check it out, and it's at 5%, with orange light flashing. Take out charger, put it back in, and it starts charging. I went out afterwards, came back about 4.30, and it says it was about 80% complete. Go sleep, wake up about 7.30am, and it's fully charged (green light). Then, I unplug charger, turn on, and it says 96%, and I notice it dropping the amount of charge in front of me (like OP's notice), until it got to about 91%.
Now, about 5 hours later, it reckons the charge is 74%. So dunno why it went down so quickly, and why it didn't actually charge... But will keep my eye on it and see how it goes...
data connection
Another way 2 keep your eye on it: check data connection (start>settings>connections>comm manager) a lot of stuff open this connection which uses power. if it turns on without you knowing .... (especially auto-update plugins (weather?)), sometimes AS also ...

that it isn't a good idea to do "old style battery cycling"
I really don't know what to think of LiPo battery management, so many different theories.
Also, something that annoys me is that I fully charge the TP2 overnight, in the morning the lights green. If I simply unlug charger and plug in back in it well go back orange and stay orange for a good half hour... and I can start again a few times...
To be honest, I had to hard reset my device couple of times and haven't had time to 'fully' recharge it after the resets.
I guess I will give it a few days of full charging and then check on the battery.
But, I am not joking when the 1% battery meter just drops numbers faster than a meter at the gas station.

I had this problem when I have push mail turn on. If you disable push mail and set it to receive like every 15 mins, it save the power a lot.
Try the advance config to auto disconnect every x mins, this will helps as well.
Hi HaveryR and others,
yep your source isn't to bad. Beginning with full charges (6 to 12 hrs instead of 3 like the manual says) isn't about the old charge-memory story (because Lithium-Ion battery don't work this way, only the nickel-cadmium and nimH do) but about fully charging cells.
I mean the best way to look upon this is like a pile of bricks on top of each other (all different cells if you wish). So the first time it is important to give all the bricks enough time to charge - so even when it says 100% it does not mean that it has (you're indicator is a feedback of a reading by your cpu). So not all the bricks (let's say) have the same quality (yesyes even in this day and age of hight teck).
So you can also take this parallel to discharging: if you discharge fully, you risk that one of these bricks get busted and so will NEVER recover.
So i agree on this with your source a LiOn batter is bettery served with frequent partial charging and must NEVER be drained completely
Greetz,

Guys,
I put the TP2 on for charging the whole night (about 9 hours). In the morning the LED was green and the battery meter said 100%. I took the charger off from the handset and re-inserted the tip in. Guess what? 95%.
AM not sure if it is a battery problem or handset problem?
Its come down to 73% with just one phone call of 5 mins. Mail is on, but its on manual and havent pulled anything since morning.
Any idea?
I have purchesed HD7 4 days ago. It never charges 100% even if i leave it on charge for whole night.
Any solution.
how do you know it doesn't? the battery icon isn't exactly specific? but if it doesn't, take it back to the store you bought it from.
The phone stops charging before 100%
Just like other phones it has battery indicator in the form of cell/battery.
It should appears filled/full when charging is full and as the battery drains it should gradually appears empty. Now the issue is that it never appears full. The extreme right side of the cell/battery always stays/shows empty.
In other words we can say that the phone stops charging before 100%.
Beside this the indicator works fine and the battery life is also ok.
I bought this phone in UK and currently working in dubai so I cannot take it back to the store.
This happened to me, for the past week+ (I bought the phone on 28th).
I don't know why but an Overnight Charge didn't seem to be long enough for it to charge fully, it was always nearly charged.
However, This morning it seems to have charged 100% so maybe it's just a matter of time? Maybe the battery isn't in sync or something when you first buy it.
Think the battery icon is a bit dodge. As long as you get the green indicator light you know it's fully charged. If it's still orange then still needs topping up.
I've not had a problem charging myself but what I have found is that sometime the indicator says it's nearly dead. Reboot and sudenly there is an increase in amount of battery left. Very odd.
Maybe you need to wait a few weeks just to let it settle.

That isn't acceptable for obvious reasons, so I hope that isn't the case.
P.S. 14-30 day return/exchange policies.
All right Dudes!
The problem is fixed. Simply fully charge your mobile phone and then full discharge till it turns off by its own. Repeat the procedure three times and you are done.
Good Luck
I have the same issue, if you turn the phone off and back on when the light turns green, the battery icon is then full.
So seems like a software issue to me.
My HD7 is going back tommorow anyway, keeps resetting itself and when trying to video in 720p it looses focus!
I previously went back to O2 store the day after i bought the phone about the original charging issue. They were going to swap the phone but then had no stock. Then my above issues topped it today so took it back and surprise surprise they were out of stock! Apparantly expecting a delivery tommorow but they don't know what they receive till they get it (BS i reckon) so if they don't have any in tommorow I'm getting a refund and going to go for a Venue Pro or just stick with WM 6.5..

How do you "full discharge" the phone? Use it until the battery is complete dead and charge it up again x3?
Yes, use it till battery is fully dead and charge till charging light turns green.
That never worked for me either, infact last night when the phone was flat, I have left it on charge over night and it went green, but showing about 50% charge, turned it off and back on and its then full.
My phone is doing this as well, now. Charges to full on teh charger. Take it off, adn it goes straight to 75% charge - viewable in the Battery Saver by battery level. It's impossible to charge it fully, and battery life is TTEERRRRIIBBLLEE.
Either something is wrong with the phone or firmware, or the OS. Not sure. But I can't use the phone like this. It's as if it has a 920 mAh battery in it. Obviously that shouldn't require anymore explanation.
---------- Post added at 11:25 AM ---------- Previous post was at 11:14 AM ----------
Follow-Up: I'm convinced it's a bug in the WP7 OS. When you charge to full, and take it off the charger, it instantly drops to 75%, then if you put it back on the charger 20 minutes later it goes to 93%?!
Problem is, the OS is set to shut down service, etc. when battery power is low (even beyond the battery saver setting, IIRC), so the bad information the OS has can hamper usability. It's basically cutting 2 hours off your battery life when you unplug the phone after a full night/day's charge.

And kill the battery, forgot to say.
Charge on the wall charger, not PC USB.
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.
Sent from my SGH-I777 using xda premium
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!)
Hello everyone,
Just got myself the HTC One m8 yesterday and am in love, but I have one small question.
When you go to power, and history to see the details of what your battery has been up to, is it normal for it to always basically reset when you either turn the phone of/reboot or plug a charger in, even for a short amount of time.
For example, I charged mine over night and took it off at 6am, went through the day and was keen to see how long I'd get from a single charge, get to now (9pm) and decide that I wanted to put some music on it, plug the usb into my laptop and transfer some tunes, unplug. Now when I go back to the history the graph just starts from 70% like its been reset and all the previous graph movements etc are gone. Attached picture is after unplugging the usb after being on for about 33min
I previously had a Samsung s4 and the graph would only reset once the phone was fully charged. If you plugged it in the graph would rise as far as you charged and continue giving information until it had been full recharged and then the graph would start again.
Is this normal for the M8 or is mine being silly?
Any help would be appreciated
Cheers

Yes, it is normal for it to reset.
It is for power history since powering up, or since your last charge.
yeah, that's normal. And I don't see a way to change it to since "last full charge" to 100% My Moto Droid would always show since last charge from 100%. If you plugged it in for a little bit, it would show that time on the graph too as charging. I'm sure there's 3rd part apps you could use that would possibly be a better fit for you (Gsam battery monitor) is probably the top one I think. Also, "better battery stats". Gsam is pretty good and monitors all kinds of stuff too, wakelocks, cpu usage all that good stuff.
