Tilt battery voltage not sensed by phone?

I have this strange problem that just cropped up. After a full recharge the other day the battery showed normal draining. When I tried to recharge it wouldn't; neither from the wall charger or usb by computer. So the battery showed steady drain unless charging, but never got more charge. Finally when turning on the phone on battery alone it shows 1% charge, and there's nothing I can do about it, the phone will turn itself off.
Diagnostics: I measured the battery voltage and it is ~4.2 volts. This seems like a full battery yet the phone doesn't see it.
I measured the voltage at the battery terminals in the phone while hooked up to charger which was ~4.2 volts. So it seems the battery is being charged.
Why is the phone not seeing the battery charge? Is the battery dead even though it measures 4.2v?
I did run the gps before this happened using gps tool, bit I think I turned it all off. Anyway more than one soft reset didn't help.
Thanks,
Ed

No real answer here but perhaps something to try:
I am dealing with another member who has a similar problem.
http://forum.xda-developers.com/showthread.php?t=377675&page=2 From post 17 onward.
With battery in, the orange charge light comes on and all seems normal. However with a few seconds of turning on the message that the main battery is critcally low comes up and the phone turns off. He has tried another battery with the same result. This happens even with the charger connected.
(EDIT: I have now read that his has - for no obvious reason started to work ok - Now even more convinced it's a charging circuit lock-up issue - given time and possibly a bit of battery fiddling and it comes good in the end - see No 2 below)
Now I'm wondering whether this could be one of two things:
1.
A hardware fault - possibly in the charging circuit or more crudely one of the battery circuit board connectors is not connecting.
OR
2.
The circuit that controls charging has to put it crudely become "stuck" in a similar fashion to those who get the RLOD red LED showing when they connect the charger. A commonly accepted trick for overcoming the RLOD is to connect the charger and wriggle the battery on and off the four contact pins. This presumably has the effect of forcing the charging circuit to re-set itself. I just wonder whether it might have the same effect in your situation.
Mike

hey.. that would be me with the similar issue.
i just tried a couple more things.. check out the thread.

More info.
Battery in and out holding the power button had no effect. Phone runs fine while plugged in. Plug it in and after 5 seconds the amber LED turns to red. While plugged in the red led will flash amber every so often.
I measured the battery voltage as I turned the phone on, it dropped to ~ 3.98v, then came back to 4.1v as the phone turned itself off. It gets all the way to my Today screen before going off. Just sitting in the phone with it off is 4.1v. Hook up the charger and the battery sees 4.18 and rising after 20 seconds. These are direct measurements at the battery terminals while in the phone.
So this looks like a software issue to me. The phone is charging the battery and there is plenty of power to run the phone, the phone somehow doesn't see it that way. It sees a dead battery. Well, I guess it could be a voltage sensor gone bad , somewhere somehow. Next step is to hard reset and see if it makes any difference.
edit: While plugged in and the screen on, the led stays amber. When the screen goes off(set for 2 minutes) the led turns red. Screen back on, led amber. I just set the screen not to go off while plugged in(charging), we'll see. The power is showing 7% now and says charging, too early to tell if it's rising or not.
edit 2: It stayed on the charger for several hours and never moved past 7%. Tried a hard reset with no luck. Next step is to send it to a repair shop(I bought it used) and hopefully spend only the $95-$125 they quoted.
Will keep you apprised.

Att Tilt Power/Battery Issues.
I am having somewhat similar issues with my Tilt, with the power/battery problems as described previously. I woke up this morning, and attempted to turn my phone on, and it wouldnt come on at all. I then plugged it into the ac adapter, and the LED comes on, and goes green. I waited a few moments, then powered the phone on to take a look at the battery life, and the phone boots up, then reboots during the splash screen. After it reboots itself, I check the battery indicator and it shows 1%. If I exit the battery screen, and re-enter it, it will say 100%. Now, as soon as I remove the charger from the system, it automatically powers down. I played with it for about 15 minutes, but needed to head to work, so I took the phone with me, and attempted to use my car charger. Same problem. Now, I figured, fine, I'll see how it behaves while I am at work, so I brought my charger to work, and have it plugged in at my desk, and if I leave it plugged in and on, it stays on for about 5 minutes, then automatically reboots. LED stays green, but phone will not stay on, if unplugged, or plugged in for longer than 5 minutes. I have never dropped it, and have babied the phone like no other, concidering I paid $400 for it. I'm a little bummed out, but cant determine if its a battery or hardware problem. Any advice/input for me from any of you guys? before I head to the ATT store, and cry for a new phone? Thanks a bunch for any responses to this.
*UPDATE* After I got off work, I went into my local ATT store, explained the situation, and was given a brand new replacement phone in like 10 minutes. I was under 30 days owning it, so he just swapped it out, barley any questions asked. (altho i explained my situation in detail as it was). So.... hopefully it doesnt happen again, or else I'll have to use the warranty. Anyways, Any insight on what may cause this would always be helpful for both myself and the community. =)

new news
EDIT: They got it Monday and I got it back Friday. Good turnaround! They fixed the problem, it works perfectly now. I recommend these people.
Ed
Sent it off to Cell Phone Repair(CPR) in Chicago that gave me an estimate of $95 (inc. ship. back) based on my description. They just called and told me it was corrosion around and in the power/usb port. They got it yesterday and will send it back repaired tomorrow with a 90 day warranty. No more saunas for this phone(it was only one! )
I'll let you know if they work out well or not.

Battery charging meter incorrect until reset

Has anyone else experienced a problem where battery meter sticks at around 65% despite being fully charged. When soft reset it goes to 100%.
It's not a battery cell issue - battery life is fine. It's simply a meter misread.

Not that i have noticed although ill say that the battery meter on the Diamond isnt all that great...its not really a good indicator as to how long the battery has before it goes dead.

Yup, mine tends to stick at 80%. At least it did in ROM 1.35. Burned yesterday the official 1.37 and we'll see how it goes...

sometimes, mine is also doing it...still cant figure out why thou...

OK, with the new ROM, the phone connected to the PC charged smoothly from about 46% to 100%. I'll see probably tomorrow if the charger makes any difference.

How long do you find the battery takes to charge from around 15% to 100% using the power pack, not computer connection???

Hi Guys,
Does anyone has more info about this ?
When i charge my device (from charger or by PC Usb), it won't go pass 89% battery charge, therefore never warns me when it's complete.
I know it charges to 100%, so it seems to be a problem with the software.
This is quite annoying, has i never get the "Battery Charged Warning" while plugged in.
My ROM Version (Original) 1.37.410.3 PTG
Cheers and thanks.

Anyone still experiencing a flakey battery meter? Sometimes mine will read 90%. Then, within two minutes it will be down to 45%. But if I soft reset, it will go back up again. Some days it's all over the place and I actually have no idea what the battery level is.
I'm using QuickMenu. Anyone have any suggestions or similar experience?

Happened to my unit as well. It doesn't happen all the time though. Sometimes it will charge up to 100% just fine and other times it hangs somewhere between 70-90%.

I've this problem, the battery meter indicates for a lot of time the same value (eg. 98%) but if i'll reset the phone i can see the real value (eg. 45%)
it's very strange

depends on what current the powerpack is supplying, it will probably be either 500mA (0.5A) or 1A. Obviously the higher the current the quicker it will charge.
A PC USB connection can provide 500mA maximum, where as a mains carger will supply 1A or 2A (think its 2A if you have a proper Diamond charger).
A car charger will vary, when the engine is off you will get 1A if you are lucky. With the engine running you will get 2A, but during the engine starting you can get a peak of up to 5A (phone killingly good).
All of these measurement can vary!

i have the same issue, too
yes. my battery meter is incorrect, too. exact same behaviour as you mentioned. 65% -> after reset 100%. nearly all the time. that's very bad, because my battery lives about 1 day without charging and in the evening i don't know how full or how empty my battery is. sometimes the remaining 8 % are real 8 % and sometimes (after a restart again) the shown 8 % are more then 30 %.

I've tried about 6 roms and get the same thing with all of them. It happens infrequently but is still annoying. Basically, if I'm suspicious of the battery level, I soft reset to verify.

it's "normal" that behaviour, because also battery check is made by OS (WinMobile) at prestabilite polling times, search in the registry for "batterypoll" and you'll see a value expressed in seconds (I suppose they are secs), try to lower those values and see what happens, of course shorter polling times drain battery faster
bye,
davide

Any solve for this now?
I also have this problem, sometimes only but still very anoying.
A soft reset seem to be the only solution at the moment.

It happen to me always too!
It was 40%, after I played Monopoly games for 1 hour, it still showed about 39%. When I soft-reset, now it show only 25%. What a huge drop!

im also getting this problem.. anyone has gotten a solution to this yet??

Maybe worth a try.
http://www.pocketnow.com/index.php?a=portal_detail&t=news&id=6369

I think that why TF3D doing reset during night while charging...
I disable TF3D every night, so no reset at night but as side effect sometimes battery does'nt arrive to 100%

My diamond has sometimes the same behavior. The battery gauge sometimes showes only 50 percent or so and after a soft reset it showes full. I had this issue a few months ago, too. The the battery gauge showed correct values and now I have the same issue again.
I am pretty sure it is some kind of a software problem, but I have no idea which software disturbs the battery gauge. I had this issue never with my touch, but only with the diamond. I anyone has suggestions ülease let me know! Thank's a lot.

Replacement battery issues

Hi,
Just purchase 2 HTC HD2 replacement batteries from ebay (Non original)
and facing a problem in charging both of them.
When I power up the phone it shows 80%, but when charger is connected,
it does not show the charging icon and the notification LED keeps blinking between amber and green.
Any one got any idea? Both the batteries defective?
I use a meter to measure the batteries, one got 4v the other 4.02v.
Seems ok but just cannot charge inside the phone.
Help and advise needed. Thank you.

Got the same issue here. They will charge up to 68% then stop.
Have to turn off phone and plug in again to charge the final bit - OR - take them out and put in caddy charger.

Battery replacement charging problem
I also have the same problem but this issue happen only if you use the device while charging the battery. If the issue occur try turn off the screen (not power off) and wait around 3-5 mintues then it continue charging the battery without any problem. The problem is occur only if we use the power too much such as Telephone call, Wifi, GPS then it back to blink green and amber again and again. Howerver I found out that sometime after soft reset the battery report it have been charge during green and amber blinking (in my case I upload youtube of 120MB and take quite a long time around 2-3 hours the battery indicate 6% and not increased until I softreset them then become 72%)
Howerver, this is almost not acceptable since it should be charged normally in any condition.

Do you guys think this is due to "low quality" batteries that could not be charge properly in the phone. Can only be charged using cradle....??????

same issue here, except mine will go amber/green regardless of power % left.
I have seen mine doing amber/geen even when it'[email protected] 10% with screen off.

That would all seem to point at the phone drawing more power than can be put in the battery at the same time.
I reported it to the ebay seller in anycase, who says he will contact the factory.

cheap ebay batteries causing problems?

My cheap battery does the same if I use cheap craddle that came with it. However if I use original charger and stock cable it is all fine.
Oh yes and original battery used in cradle does the same orange/green.
However in any case living it for 3-4 minutes starts charging process.

When it's charged up fully it's def a massive improvement on the original though. I can get almost 50 hours out of it now, the original one I had only got 24 at a push

[Q] OTA update to Lollipop: Terrible battery life, very slow charging

I just got the OTA update from KitKat to Lollipop (5.0.2) yesterday and I've noticed terrible battery life and very slow charging since then. My phone is always in its charger overnight and when I remove it from the charger in the morning it usually easily lasts until I put it in the charger at night again. During the daytime I do a lot of stuff on it (whatching youtube videos, listen to internet radio, whatsapp, internet browsing, making phonecalls etc).
This morning I removed it from the charger and hardly didn't do anything on it for the first two hours. When I wanted to send a whatsapp, I noticed battery had already fallen to 70% in only 4 hours or so - 4 hours of doing nothing while the phone was in energy savings mode! Half way through the day, with only some whatsapping, battery had fallen to 20%. When I connected it to the charger, it instantly dropped to 8%. After about an hour of charging, it was at 17% and said it would last another 6 hours before the phone would be fully charged. Usually I charge my phone in 1.5 - 2 hours!
When I did the update, I didn't do a factory reset and I would like to only do that as a last resort.
If I look at te battery statistics, I don't see any app using an obscene amount of battery life - the highest being Google Play services with 15%. But what I do notice is that "Cell standby" is responsible for 29% of the battery drainage.
Before I do a factory reset, anyone any tips?

This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC wall charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons WHEN THE PHONE IS ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)

Battery recalibration ... Many techs say it's a placebo. But, I will follow this manual, just in case.
I do confirm, though, that with L 5.0.2 charging takes longer, phone drains faster with the same as before apps and usage, phone is often hot, and I've started to get regular 'can't charge, your phone uses more power than available from charger'.
Re phone uses more power than available, it happens with all three original HTC chargers I have, so I have to use the charger from an Asus tablet (1.5A output).

I haven't done the recalibration thing but I did some measurements and I now know why it's charging so slowly, just not what is causing it. The phone isn't switching to high charging mode and keeps charging at around 400mA. This means that when using the phone, it's draining faster than it can charge. I also think it's not switching to standby mode causing the high drain. Often the phone gets hot when it's in my pocket (when it is supposed to be in standby mode) meaning something is still draining the battery fast.
I will do the calibration thing and see if that helps.

I just did the reset thing (holding power + vol up + vol down) for two minutes. It's now charging but I can see it's still not charging in high mode. It's still charging at only 400mA.
Edit: Phone says it wil take 10 hours to charge (it's at 30% now).

Annoying, I know, but I'd factory reset the phone just to make sure the update has 'taken' correctly

Sounds logical. How did you find it out? Instrumental, or through a phone menu?
I have checked Setings/Power. Mine says Charging on AC, which supposedly means high charging mode.
PS. Again, whatever it might mean, when I get a 'phone uses more power than..' error, I connect the phone to a 1.5A charger (compared to original HTC 1.0A) and it solves the problem. I'm not happy with this solution, though.

There are a few ways I can measure this. I have a "Charger Doctor", one of those inline USB voltage/current meters and I have an "Energy Meter" which measures wattage going out of a 110/220V socket. Both confirm each others measurements. The Charger Doctor says my phone is being charged at 5.1V at 0.4A, and the energy meter says the charger consumes about 2.5W which is about right (the charger looses some energy through heat and the Charger Doctor consumes a bit of energy as well).
But...
To be sure, I tested a few different (but identical) chargers and changing the charger made no difference. But - and here comes the strange part - I tested about 20 different USB cables and with only two my phone charged at 1.0A (which I assume is the M7's max charging current). With all the others it charged with 0.3A-0.5A. Only with those two cables it charges in high charging mode. So apparently something changed in the charger detection. Before the update I was able to charge the phone in high charging mode with other cables as well.
Also, it seems like it's now discharging not as fast as before, but I will be sure tomorrow after it has fully charged and after I've used it all day.
Edit: Yep, charging is at it's normal speed now. It's at 60% and the phone says it will be 1 hour and 1 minute until it's fully charged.
Edit2: Of the two cables it charges at 1.0A with, one is the original charger cable that came with the HTC, and the other is a cable that came with a Duracell Power Bank.

Well, after the three finger calibration, charging seems faster, and I think battery holds longer (or maybe I want to think it does, because still not sure).
One additional observation is in about 20% cases my phone is stuck during boot until I connect or disconnect the charger for a second. By connecting or disconnecting the charger, something triggers the power state and the phone boots normally.
So yes, you may be right about new power management in Android 5.
(I'm now on IC7.0.0 + ElementalX 20.0, HTC M7 Int'l))

Well, even though charging times seem normal now, it is slightly erratic. I can see the percentage making jumps up and sometimes down while charging.
Also, battery life still is very poor. Battery now lasts until halfway through the day while before it would easily last all day...
Is there a way to revert to KitKat? Other than a lot of annoyances I haven't noticed a single advantage using Lollipop.

Factory reset
I had terrible battery problems after T-Mobile upgraded my HTC One (M7) to Lollipop. The phone was constantly awake and churning with the GPS probing for a signal every few seconds. I'd lose 50% of my battery in a couple of hours. I went through the battery recalibration suggested by HTC support, but it didn't work well. Finally I did the factory reset. It worked perfectly! Now my battery life is better than ever and the phone will go well over 24 hours on a single charge with normal usage. Recovering from the factory reset was easier than I anticipated. Google Play Store remembered and reloaded all my apps automatically. The only headache was having to log in to everything again. Well worth the effort.

I did a factory reset as well and it looks like it has improved battery life. I'm still on my first day after the reset so I won't be able to really tell after I've used it for a couple of days. But like I said, the hard reset seems to have made a difference.
It has been 15 hours now since I unplugged the phone from the charger and it still has 43% left. But I just noticed a few minutes ago that two energy settings were set different than before the hard reset. Screen brightness was set to auto (when before I had set it to it's first dim setting), and data connection was set to switch off after a long period of inactivity. (while before it was set to always on). I've changed those settings and see if that makes a (big) difference.

Tested it for another day and battery life has definitely improved quite a bit but it's still nowhere near what it used to be with KitKat.

when i woke up this morning my m7 was 100% it's now 11;10 and it,s now 70%

I'm getting exactly the same problem.
HTC support said they never heard about such a problem and their conclusion is to send the phone to be repaired
I don't know how to rollback to previous version and it doesn't looks like to be a new fixed version on the way.
Or at list I haven't heard about it.

I also noticed it doesn't make much of a difference if I turn on energy savings mode.
With KitKat, my phone would easily last the whole day without energy savings mode. Now with lollipop I have to hook it up to a charger in the evening - even with energy savings mode enabled.
The thing that sucks the most is that my phone drains in alarming rate when playing a game, or listening to online radio or watching youtube videos. 30 minutes and battery drops from 100% to 50%. And the phone gets really, really hot. Before lollipop, it would drain perhaps from 100% to 85% and the phone would not heat up at all.
There are so many annoying bugs/features with lollipop, I'm considering an iPhone for the very first time ever as my next phone. Mind you, I've never been a fan of Apple stuff. But Android is just getting ridiculously bloated and simply doesn't work very well anymore. It looks like every update makes my phone less usable. And I hate the fact Google thinks it's perfectly fine to disable/remove stuff that people have come to depend on. Like my notes (amongst man other things). Google in all its wisdom has removed the Notes app making all my notes inaccessible. The only way to get my notes back is to install some third party app from the Play Store and have it transfer my notes to the cloud. First of all, I don't want a third party app handling my notes. And I most certainly don't want my notes stored in the cloud. I travel quite a bit and I don't have internet access everywhere I go, making my notes inaccessible again.

P9 won't charge after battery replacemnet

So like the title said i have replaced the battery in my P9, with an original battery. It has the same part number and all that. I have noticed that the phone won't charge the replacement battery, i have returned the new battery in warranty and revived another one. Same thing, the phone starts up as soon as you plug in any kind of power source to it , like a charger, but no charging notification. The notification light pulses in rare intervals (some thing of 10 secs or more) but it's not steadily on like when normally charging. And the most vexing thing is : if i replace the original battery it charges. Unfortunately the the original battery now has the bad habit of cutting out on me at random from anywhere 47% or bellow .... The phone is nearly 3 year old now.

Have you given the new batteries some time to charge? Maybe they were delivered to you fully discharged.

First one was on 85% the second on 60% or so. I kept the 1st one on charger for a whole weekend... Still nothing

Have you tried to callibrate the original battery (you say it suddenly drops if below 40%)?

Yes, I have allowed the battery to run down to 3% and the phone turning itself off. Then fully charged it while being off. So the original battery is just plain old, nearly 3y old. The problem is that the phone refuses to charge the new batteries regardless of original charge. Also it turns automatically on when you plug in a charger, not just showing the charge animation. That is not normal behavior.

I've done that after reading you'r message , but i have already done the steps not req root. And i'm not willing to root my phone.

P9 also not charging
Did you manage to find a resolution to this issues? I'm having the same problem with my P9. I changed my battery, and it now won't charge. It turns on ok, and everything seems to be working. When I plug in the charging cable, it makes the sound it usually does, the battery symbol flashes green but instantly turns white again. When the phone is off, plugging the cable in switches it on, but no charge. I've had two replacement batteries, both have the same issue. Also, the original battery is now doing the same. I'm wondering if I damaged something while removing the battery.

I think it's problem in charging IC or port.

Hi all
Had same issue with replacement battery
After replacement battery isn't charging. Problem is in bad connections
(probably from long shelf storage connectors got rusty)
Voltage was fine but temperature reading was way off (very low -2) and phone didn't charge battery
Problem is that there was no error message about battery temp.
After cleaning the contactors battery reading became normal and it started charging

Anybody ever had any solution to this problem? I have the same issue. Battery replaced - not taking any charge. If micro USB charger plugged in - the phone turns on. If it is already turned on plugging in the charger the screen flashes the % of the charge and nothing.
