Battery problems already??

Hi all
Just after an opinion really, also see if anyone else is having a similar problem with there battery??
I've had my desire now since April, and recently been having issues with the battery. When charging it, the Orange LED charge light will turn green at around 94% charge and still climb to 100%. Then when its charged (for a whole night) I unplug it, battery states 100% charge for about a minute, then drops straight to 93%. I've tried it with a few roms now, standard Rom, froyo, now on pays bravesoul release, and they all do the same...
I've tried resetting battery charge status in recovery console too, but made no difference...
Surely the standard battery can't be on its way out already??
*edit*
Info in my Sig is a bit out of date, so ignore what it says lol! Running latest pays bravesoul release as mentioned, not done any tweaks to this Rom yet!

Install JuicePlotter and then monitor the usage
report back
it should show whats using the battery when it takes a huge decrease

AFAIK the charging stops after reaching 100% (probably as safety measure)
and there doesn't seem to be a trickle charge function to keep it at 100%. This is actually a good thing 'cause Li-ion and Li-poly batteries don't like to stay in the highest or lowest regions too long.
So...charging stops at 100% and after that you're running on battery. Try charging it and unplug the charger when 100% is reached (look at the actual %, not the LED. You will notice it'll go down at the same rate it always does and no jump to 93%.

I think it charges to 100%, then allows itself to drop back to 90% (the phone still shows 100% though) and when you unplug the phone from the wall, it will drop back to the "actual charge".
If you plug it back in, it should start to charge back to 100%.

Fully charged battery drops 10% charge for unknown reason

Hey people,
I've noticed this strange effect (which I notice using the Battery Graph app to observe how my usage drains the battery). When charging the phone, the phone will increase in charge constantly and gradually as expected. However when the phone is charged, I have seen it drop approximately 10% of charge. I've seen this in 2 situations:
1. When I disconnect it from the charger.
2. On on instance before I disconnected it from the charger when I had left it for an overnight charge. However, according to the graph, it had dropped 10% charge from full while connected to the charger then simply gone back to 100%. When I took it off the charger it stayed at 100%.
I should not that neither situation happens all the time. But situation 1 is a bit more frequent.
This is also not a Froyo issue as I only upgraded to Froyo yesterday and it happened to me this morning, but has happened before Froyo. The Battery Graph app takes a reading every 5mins and it is within this 5min period that the charge has dropped 10% which would probably rule out most apps. And again, this can happen the instant I take it off the charger.
Any ideas???

your asking to get slapped asking this question its been discussed in so many threads lol heres the score, when charging with the phone on, when ur charge reaches 100% it then discharges to 90, it will follow this cycle untill you unplug it, this is called exercising the battery, and i assume it a preventative method to stop you damaging your battery by overcharging it

I will consider myself duly slapped for not checking it up. I normally tell other people they should have checked!

Charging problem! slow or no charge..

ok, over the last week or so ive had this issue, gradually getting worse...
my battery will charge to around 40-45% and then charging will slow right down.
two hours later, it will be on around 50% if im lucky, and about 3 more further hours before i hit 60% (this is some of the time, other times, it just remains on its current charge%)
if i leave it overnight for about 10hours or so, highest it goes to now is about 73%, but this is rare, usually 45-50%ish.
ive tested with htc ac wall charger, htc usb, blackberry charger, car charger and a random microusb wallcharger. all have same issue.
when tested with two friends desire hd's on different days, my battery charged perfectly, and at the normal gradient speed over the % range. and my phone reads it correctly at the 100%-98% when back in my phone after change back.
i thought it was down to my phone, just dont know if its rom or hardware. shud i factory restore, or claim on insurance?
i have another issue here...http://forum.xda-developers.com/showthread.php?p=18480603&posted=1#post18480603
which also applies to the question of restore or insurance...
thanks

What Rom are you using, i am using runny 2.2 only 62% charge in 6 hours
9 hours later on battery only upto 68% i have amazing battery life now

i'm using runny 2.2.....left it on charge for 2 hours with phone on, but wifi and everything off and it had only gone up 2% ! !
Turned phone off and plugged in charger, 30 mins later, only went up 1% ! !
72% charge at this point.
So took it off charge, put it in my pocket, went upstairs to bed, turned it on to set alarm and it said 100% on battery....weird!!
matt

Lol this is an issue with calibration. The battery is charging but the software doesnt report it.
You have to charge the phone for as long as possible so you know it is on 100% whether the software says it or not, go into CWM, wipe the battery stats and then let the battery drain fully until it shuts down by itself. Then plug it in and leave it until you know for certain it is at 100%. If the green light comes on leave it for an additional half an hour. Then it will be fixed.

ive only recently got this handset, as last one was replaced on insurance a month or so ago, and its runuing on stock rom with latest updates....?

[Q] Charge times

How long does it take to fully charge your One-X?
Mine is already charging 3.5h to get from 40%to 80%....
Using the default charger, and not using the device.
Isn't that a bit to long?? My HD2 was completely charged in 2h..

I am no expert, so don't hold me on this one, but I believe your device charge should speed up due to firmware updates and also once the battery has been 'worn' in - just stuff I have seen about.

Can anyone else provide me their charge times? How long it takes to charge from A to B?
Pls mention with wall outlet or USB.

I've noticed this as well. My Arc charges in like 2-3h to full. the One X takes about 2 hours to get to about 60% from 30% (using USB).
edit: wall charging takes just as long.

Can't be normal, right? 2h from 30% to 60%...

i think its to do with the type of battery they are using to be fair

Interesting reading about lithium based batteries
this is a quote from batteryuniversity dot com
Simple Guidelines for Charging Lithium-based Batteries
• A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
• Charge at a moderate temperature. Do not charge below freezing.
• Lithium-ion does not need to be fully charged; a partial charge is better.
• Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
• Discontinue using charger and/or battery if the battery gets excessively warm.
• Before prolonged storage, apply some charge to bring the pack to about half charge.
• Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.

And I also read that charge time should be almost 3h for a full charge(i suppose this is when device turned off). You could get about 70% charge in about an hour if I remember correctly.

Hmm not gonna turn off the phone for every charge tbh...
Sent from my HTC One X using xda premium

While charging and using the phone it takes around 5 hours to get from 5% to 14% when not using but charging takes around 3-5 hours to charge from 25% to 100%

My second charge, from 0% to 100%, with device shut down took 3.5 hours to show the green led... quite a long time since I was using the wall-charger... I hope it will improve with the fw update and after the battery has been "initialized"

Today I began charging my HOX at 1:44 (1%) and it finally reached 100% at 4:59.
I was using HTC's charger.

same here, about 3h from shutdown with 0% to seeing green LED
using wall charger

Took me three hours with original HTC wall charger and original HTC cable (no extension) to charge from 4% to 100%. Terribly slow!

EDIT 1 : Apparently BWM doesn't show accurate power draw while idle on the One X for now, so my post has become totally irrelevant
I always install Battery Monitor Widget on all my Android devices and monitor charge and discharge constantly.
On my Desire Z, if it's below 70%+ I get a charge rate of about 750mAh from wall socket.
But on my One X, with the same charger (both are rated for 1amp, and both HTC), my charge rate drops to 450+ at 60% battery life.
It's probably a software issue, but charging the One X does take noticeably longer.

I don't think it is a software issue, as the battery pack is larger than before. Also when you are active the phone itself draws large amount of current and it definitely slow down your charge rate.

When your phone is idle with screen of, it shouldn't drain large amounts of power while charging. Can't imagine that has a huge influence on charge times tbh.
And for capacity, my HD2 was charged in about 2H for a 1200Ah battery, this 1800Ah One-X batt should be full in like 3h... not 5 or 6h...

The official wall charger took 2.5 hours to fully recharge the One X

Ok after an amount of charges, it now takes only 2.5h - 3h anymore for a complete recharge.
Official wall charger.

Did a charge on mine this morning from dead, took 2.5 hours to get to about 90%, left it for another hour but it didn't go up the last 10% stayed on 90 even after the extra hour. Off the wall

I'm thinking the same... I don't mind turning it off on a night for the first 2/3 charges but personally this is my only phone (don't have a house phone) so will be keeping it on through the night in case someone needs me in an emergency etc...
Was interesting to read that batteries prefer a partial charge and do not need to be fully charged; which is good actually as mines got around 18% left and I'm about to stick it on charge for the next 8 hours.

How to do you charge your One X?

Just wondered how most people are charging there One X? Personally I always turn it off and allow it to charge until the light goes green. I've never charged it when it's still been turned on.

I've never switched off any of my android phone's whilst charging. What happens if you get a call? I also try to alternate between charging on my pc and the wall charger.

Yeah fair statement, I had thought about that. I wasn't sure if it was bad to say plug the phone in at 11pm until 7am (8 hours) charging whilst it being turned on? I assumed if it was going to be plugged in say for that long that you should turn it off.

I just plug it in - went to bed on 80% last night but fair enough I'd hardly used the phone all day (standby battery life is incredible)

So you stuck it on charge just to boost that extra 20% yeah? How come you didn't just leave it until it was low?
Should of asked if people would partially charge it or if they always ensure its fully charged.. Can't amend the poll now though.

I was thinking about trying that - might do that tonight and see how it lasts...

I plug it in to a usb cable

i charge my hox every night on the wall charger while turned on. even if it has 80% left. i am to afraid that my battery level goes under 20% (i heard that falling under that level can damage batteries).

Where did you hear that? Mines dropped to 14% before and I then turned it off and charged it and the battery still seems fine. Wasn't aware you could damage the battery if it got too low...

I killed my battery first 2 charges - never have in the past but thought I would this time

I have always charged with the phone on, all my phones since way back having an analogue Nokia mobile and never had any battery issues. Only time I have ever switched my phones off is if I was getting on a plane or the battery got really low and didn't want it to go completely flat.

Just plug it in whenever. Modern li-poly batteries doesn't have memory and charge cycle life is based on full charges.
Part charges actually increase life due to low % cycling

Agreed.
One thing to note is that you should never let it completely drain the battery, the phone will switch itself off once the battery reaches critical level then it needs a charge. I'd recommend charging it when it reaches 5-15%.
Also I'd never leave it charging over night it interrupts the cycle, if I have to charge it over night I set an alarm to go of after a few hours and unplug it.

i have 3 or 4 charges from different makes-and only htc charges the quickest. the worst is usb cable and car charger. but due to usage i need to charge twice a day

Dude...
I always charge overnight - purely for convenience really.
Can you explain the above to me? I'm not sure what you mean by it interupts the cycle?
How does it effect the battery ?
Thanks alot

You are 100% right most modern phone battery’s don’t have memory any more so no need to worry about it, and no need to do full discharge and recharge cycles to maintain battery health, and if they do they normally tell you in warning labels or in instruction manuals, for example I recently bought a new shaver and it tells you to do a full discharge and then leave it on charge for at least 12 hours every 3 months to maintain battery life.

batteries have safety features built in so don't worry. What for you looks like 0-1% left - what android is showing you, might be actually 10-20% as seen internally by the battery.
Also, I have completely discharged my phone once, I simply left it at 1% and waited until it shut off. Then I charged to 100%. From then on, I charge whenever I want, phone is always ON.

Ebay 2m cable (the HTC one's length is a joke).

I use a charging cable.
My friend sticks it next to his head and uses his brainwaves to charge it.
Both seem to work fine.
Im really sorry for this post. I could not resist.

You guys are ridiculous. Just plug the phone in and it charges.
