anyone else with horrible battery calibration

Well Im not saying the battery life itself is bad, but well for example, I just drained the battery completely (phone shut down by itself) and within about 2 minutes of putting the charger back in the indicator read 70%.
Im currently using the method where i run it down to 1% then fully charge, rinse and repeat. (Just started doing this)

no problems here, but apparently half the people in the battery threads have issues with battery life.

hmmm, well I just want to get this right because it gets annoying when it says 100% battery then goes down in about 20 minutes

I've had issues with battery life indication on my Omnia 7.
I can have it showing 70%, then it would suddenly drop to showing around 10%. Then by turning off and on several times it will sort itself out and show the correct amount.
This has only happened once or twice mind...

No problem here on my HTC 7 pro. Though I did calibrate one battery and not the spare, both perform the same.

I have no problems either on my omnia 7

No issues on my Focus. Maybe this is a device specific issue?

No problem with my trophy but a good practice to keep you battery in shape is to start charge at 15-20% (dont leave it until is dead is bad for the battery) and dont charge it to 100% ...stop charging at 90-95% ...
That is what i do with all my mobile devices and rarely i have probs with my batterys.

[Q] Weird Battery Problem??

This happened twice today..
For e.g: If my battery is showing 15% and then i restart my phone it suddenly shows 50% remaining..
Am using Battery Indicator to show me in % how much is remaining (though even the htc battery shows the difference in this case)
Any idea why is this happening and how to solve this??
Oh and how to stop the: Show Me app?? Keeps restarting and sucking my battery..

Could someone please help me out here with this weird problem??
It keeps happening everytime i restart my Sensation..

Try wiping your battery stats from CWM.Then charge battery fully>drain fully>then charge again it should be calibrated. oh and use startup cleaner in the market.

Its a 1 day old Sensation.. Havent rooted it yet..

I saw the same with my mine. I allowed the battery to drain until the phone shut off and recharged over night to 100%. I did that for a few cycles and mine seems fine now.

The battery % indicators only show what the phone software *thinks* it currently is.
The Sensation battery ranges from approx 4200mV (full) to 3000mV (empty).
The problem is sometimes the phone thinks those numbers are different. E.g. when you turn on your phone for the very first time, or flash a new ROM, if your battery was half full at 3700mV the phone would then think that was the 100% level (why they say charge a battery fully for a long time before turning your phone on for the first time).
This leads to various funnies such as a battery seemingly staying full for ages (the phone thinks 100% is much less than 4200mV so until you drop to the phones level your battery %age doesn't go down), and seemingly rapid drains where you end up with less than 10% left - but probably find in reality if you left it your battery would go on for ages at 0%.
Over time it learns, but best to wipe your stats after a long charge so it knows that 4200mV is 100%, and then don't charge your phone again until it physically runs out of juice so it knows what is 0%.
Another useful tip is to install the free BatteryLife widget from CurveFish from the market. That shows you the current voltage level as well as %age, so armed with the knowledge that full = approx 4200mV and empty = approx 3000mV you get an exact idea of how much you have left.

Mine does the same thing even draining/charging for few cycles

Yeah... I went to sleep with 100% charged and when i woke up it was yet 100% charged.. And when i check the battery stats it shows 0s but i was asleep for 8 hours.. Any way to solve this on an unrooted phone?

I had the same problem today too! Thought my battery was kicking ass...turns out it was 18% when I restarted my phone

What did you do about it?

Anyone know what to do about this to an unrooted phone??
Or is this a defective piece and i should get a replacement??

Mines has done the same but I haven't had the chance to calibrate it yet to know if that'll help. It has helped on previous phones. I don't think your device is defective though.

How do you calibrate an unrooted device??

I think it calibrates itself after a few charge/discharge cycles. Always charge it a lot longer than when the green light comes on (because if the phone thinks the 100% level is a lot lower than it should be, that green light may come on early), and for the first couple of charges let it dry out rather than topping up.
And install that BatteryLife widget from CurveFish, then you can look at the voltage. 4200mV = full, 3000mv = empty, regardless of what your battery %age says. Mine currently says 51% and 3753mV.

Having the same problem here, restarted my phone afew times now and the battery % keeps going up, then dropping rapidly! :s

[Q] Erratic charging behaviour

Hi,
I've been experiencing some weird, erratic charging behaviour in my One S. I plug it into the standard charger and leave it overnight. Since about two weeks, this rarely gives me a full battery in the morning. When I look at the stats, it usually charges to almost or completely full, but after that I get a lot of alternating periods of charging and discharging. Again, this is during the night, nobody touches the phone during this time (no, I have no children and the cat is locked up for the night in another room). I tried a different cable, but the result is the same.

So: why the charge/discharge cycles? And above all: why does the phone decide it's unplugged at about 4:15 although it's not?
Can anyone help here?
Edwin

Last night it was time for the periodic complete discharge of the battery. Now the erratic behaviour seems to have stopped, at least for the moment. I'll keep you posted.

Having the same problem.
I have the same problem on my One S. I also noticed that when it's charged to 80-90% it starts chaotically flashing the orange LED (alongside the battery symbol changing to charging/not charging) while it connects/disconnects to the charger.
Did you have any luck with this?

I did, but I wanted to know if that offered a permanent fix for the problem or it reappeared.

So I did the same thing, indeed the erratic behavior stopped when I was recharging it, but it took me 5h30min to get the phone to 89% battery. It went well up to ~40% but after that it was like 10%/hour.
Then I did a factory reset and in 2 hours it went from 59% to 97%. It seems to have worked better but the erratic behavior reappeared when the charging was at ~87%
If you found a permanent fix for this, would really appreciate you sharing it.

solution
Ok so I finally found a solution. It seems the stock charger output was the problem (5V, 1A). I bought a 5V, 700 mA charger and it now works like a charm, charges from 0% to 90% in ~2h 15 min. And battery life... no complaints whatsoever.

[Q] Restarting the phone gives MORE Battery?!

Yes, this is exactly what I get lots of time. Today, I had been charging my phone for around 3 hours starting from 14% battery. Till now it had reached around 55 % when I had to remove the charger and I put my phone somewhere. Then after some minutes I connected my phone to the PC to charge via PC now, as the charger was unavailable to me for the moment. I found that the phone had been turned off automatically. OK, so I turned it on but I saw that the battery is 100% !!
Similar thing happened yesterday when I was charging phone and decided to restart mobile thinking of getting more RAM, for it had not been restarted since a while. I restarted at 20% battery and turned it on to find that it was above 50% !
Why is it happening? Does my battery get charged quickly but phone does not tell me or is my battery behaving funny? (actually, not funny at all)
My brother's HTC Amaze charges from zero to 100% in around 2.5 hrs and other brother's Xperia Arc also charges from zero to 100% in around 2 hrs.
But my Sensation normally takes 5-6 hours.

This is a known "issue" and is due to (closed source) htc drivers. Those jumps are rather large though, could also be due to bad battery calibration; something to be expected just after flashing a rom.

I have never flashed or rooted.. didn't they give a solution?

Actually it happens even if you're completely stock. It's a known issue in everyone sensation, i think. I also think It won't give you more juice as percentage will reduce faster to where it should be.

That's what I experienced yesterday.. it dropped down real fast.
As mentioned above, it may also be a calibration issue. I am saying this because I sometimes charge with charger and sometimes with PC (USB charging Mode), and even sometimes switch between these while going from 0-100%.

I think it doesn't matter how you charge or deal with your phone. I don't think that battery calibration will solve it. If you reboot it'll increase your battery percentage, even if you don't use a charger.

it is a common htc issue with battery percentage
it happens with my device too
while charging if i do a reboot it jumps to a higher percentage

Battery/Phone Shutting Down

Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do

Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.

I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast

Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
