Hi guys,
I've let my archos 101 charging overnight a couple of times but it never reaches 100% (more like 95%)
Is this an overcharge protection or something? So would the device have charged to 100%, then stopped the charge and started discharging?
Cheers

It isn't an overcharge protection, it's a known issue since the firmware 2.3.20.
The battery doesn't load to 100% and the battery life is shorter.
That's the reason, why I did a downgrade to the firmware 2.1.08.
aha, that might explain why my battery life isn't as great as a lot of reviews show...
how can I downgrade? Is there loss of functionality when downgrading?
thx
B
For a downgrade, you have to follow this tutorial.
After the tutorial, download the 2.1.08 firmware here: Klick!
Then copy the file to your Archos and install the 2.1.08.
The only stupid is, that all your apps and saved files will be deleted, so you've to backup them.
The functionality is the same. The 2.1.08 firmware is more stable and the battery loads to 100%. The battery life is more than 30% better, I tested this on my Archos 70.
I recommend the permanent root (Klick!), because you can delete the Archos updater, so you don't see the notifications of an update to 2.3.26.
how bout installing urukdroid? would this solve this issue as well?

Been using the g tab since December and have always been impressed by its battery life. Only issue was the battery meter never seems to reflect the true battery level. I had times when it just shut off without warning with the battery meter at 100% while other times, it drained rapidly to 0% within 20 minutes.
I know the general fix is to delete battery stats with recovery (which i have been doing frequently) but that still doesn't quite solve the problem. As such, i decided to test the exact battery life of the tablet. I am quite shocked at just how good it is o.0.
I've had a (1hr 17 mins) video looping with wifi on and connected for exactly 9 hours now as i am typing this. The battery meter still reads 100% but i think it will turn off/drain rapidly soon.
I am on TNT Lite 3.1.4 btw (old but gold).
Update: Tablet just shut off after 10h and 56 minutes on video loop + wifi. Video was stored on tablet memory.
Issue: Battery meter never drained and was 100% till death (i plugged in and rebooted and it read 100%). I had just wiped battery stats before doing this experimental run. Any suggestions to deal with the battery meter issue?
I had a similar problem with another tablet after wiping the battery stats and still don't know if that was the issue or not. From my recollection, you were supposed to discharge the tablet completely and then delete the battery stats (or was it charge it completely?). Is it possible you deleted it in the wrong state, so it thinks an empty battery is full? I always wonder if I might find a similar fix for the other tablet or if the charging hardware simply failed (not a gTablet -- a flytouch2 type device).

From what I've read about calibrating the battery on other devices (specifically in the EVO forums), you're supposed to charge it until it's full, immediately wipe the battery stats, run it until it's dead without turning it off at any point, then charge it until it's full with the device off. Turn the device on and it should be properly calibrated. I'm not sure if this will fix your problem, but it's worth a try.
If that doesn't work, you could try flashing a different ROM and see if the problem persists (backup everything in clockworkmod first, so you don't lose anything if you want to go back to that ROM). If the problem goes away, it's probably an issue with TNT Lite 3.1.4. If the problem persists, it's probably an issue specific to your gTab.
Thanks guys. Ill give it a go.

I've been having an issue where my battery show that it is discharging but then it abruptly shuts down when it hits ~50%. No warning of low battery voltage.
I'll try this calibration and report back with results.
Update...8 months on.
My G tablet is now running Flashback 10.3 (finally HC is stable enough).
Battery still does not reflect drain, stuck at 100% every time. (i've been told its a kernel issue)
On Flashback 10.3: Looping a youtube video (1hr 14 mins) with HD on, sound off, wifi on, brightness set to automatic in a dark room. Tablet died after 9hrs 21mins.
This is 1.5 hours shorter than the result i obtained when i looped a internal storage video, wifi on, brightness automatic, sound off 8 months back on TNT 3.1.4 (froyo).
I'm pretty impressed given the 3700mAh in our device (compared to most 5000mAh tablets). Anyone done any tests? Do share.
Hi there,
maybe this is a stupid question, but last night I updated (via Kies) to 2.3.4. While the instructions in Kies said that I should do this with a fully loaded battery, I did it with 60% charge.
Now my question is, if this will have an effect of the calibration of the battery. Are the battery stats reset when a new Android version is updated? And will the battery stats now think that 60 % is 100%?
No they are not recalibrated .Calibration takes a few days .

The answer is: NO
No recalibration process takes place after regular Kies update. And you don't need to to update with fully loaded battery. Theoretically it is sufficient to have enough power for >30 minutes of operation.
make sure if you want to calibrate a battery to leave it to the max and dont discharge it during the charge....and when leaving it to drain do it again without reboots or interuptions....and always do that a few charging cycles and you be good to go...
just answering the calibration part
I just saw this yesterday i've done a fresh install of the latest firmware from official site and just realized that my battery is discharged so i plugged my Archos 70 Internet Tablet to the charger and left it charging one night and yesterday when i just unplugged it and started my tablet showed me just 97% charged .Has anyone got the same problem?
Your battery gauge is lying to you (and it's not such a bad thing).
Basically, all modern device battery gauges are inaccurate/deceptive in one way or another. The manner in which Archos' battery gauges are inaccurate/deceptive seems to possibly vary between firmware versions, leading to much wailing and gnashing of teeth on the forums over probably illusory battery drain "bugs".
What I want to know is whether it's possible to reset battery stats, and if so, how?
Have you searched for that in the DevForum?
It's explained there
I used battery calibarator (needs root) from market & is a little bit better since or maybe not & charged full to empty a few times too.
Hi.
I'm, running an Archos 70IT 250Gb version. I bought it from eBay and all seems to be ok, except the battery.
Let me explain. When I charge it fully, the green light starts flashing. I turn it on and the battery states around 87%, (sometimes slightly higher, upto 91%). When I unplug the charger, it jumps to 100%.
But, after a short sleep, it drops back to around the 87%, and then back up and down.
The battery still seems to last reasonable well, for example, I watched 6 episodes of Primeval the other day at about 45mins each and the battery was still ok. Got the 'Lower than 15% warning' but still ok.
I've tried some of the calibration tools from the market and also deleting the batterystats file in root.
I'm using the latest FW with Root and O/C, think it's a Chulri rom, (it's called "archos_gen8_root_oCkernel_fw2.4.82").
It's not a world ending problem, but it just bugs the hell out of me.
Thanks in advance.

I have the same behaviour on my 10.1IT and I've come to consider this 'normal'. Everything functions okay and battery life is as it should be (8..10 hours).
The BatterySnap app will show the exact charging levels.
Hey runnin uruk and have same issue/annoyance but i use es file explorer to delete batterystats.bin and unplug from power it will go back and stay at 100 and decrease appropriately, unless, depending on what performance and swap or compcache is, it will drain super fast, but this is false reading as you can use an app like memory booster and free up some ram, it closes whatever may be draining, then delete battstats.bin give a sec it will reset, a reboot also will reset the battery reading... hope it helps much thanks to everyone on xda

Battery level isn't exact science on this tablet.
It is more an estimation of the remaining capacity.
Is it running the latest Archos Official release? (2.4.83) Some releases have been known to have an unreliable battery gauge.
Best thing to do is not rely on the % it shows you, look at the voltage in a battery app, the a70h is max at about 4.189 volts is 100% it will show 80 % battery at 4.111v witch we all know isnt correct, but the voltage usually doesnt lie.. most emperical battery calcs do this

Hi, all
I have a problem in my SE xperia mini, after rooting with zergrush version 4 and running the script the fixes overheating problem, I got my battery miscalibrated,
the battery indicator goes from 15% to 1% in a second then warning of shutting down,
I have tried the two highest rated battery calibration on market but it gets worse
It started to shut down at 11% then at 15% now at 17%
is there any tool that can fix that problem, please note that I'm running version 4.0.2.a.0.42 and I only rooted the phone without flashing any custom ROMs
thanks a lot in advance
There is no such thing as battery calibration for Android.
That is because batteries do not have any kind of memory effect. NONE AT ALL.
Even this batterystats.bin file doesn't affect anything, it only contains information about what has used battery and how much, only for the battery usage page.
Don't believe me, go check the link in my signature.
why nt try another battery buddy...?

Thank you, so can I ask .. how to adjust my battery indicator ?
it shuts down at 15% after rooting, is that a coincidence ?

thank you but I don't think it is a hardware issue but I may try that if software solutions failed
ok buddy i also have xperia mini and i faced the overheat problem and i was on v 62 firmware so i downgrade to v 42 then root the phone and used the gscript and
now the phone works fine no problems now you tell me that u have a kind
battery problem so as you said the problem is software and you have 2 possible
solutions :
1- try to unroot your phone
2 - upgrade your phone to v 62 and dont be afraid the overheat problem
wont come back in the new version 62 or any time
try and tell us the results
I have the same problem but I'm getting 52% to 0%.
I tried battery calibration with app and cwm battery wipe. No success.
Read somewhere today that charging battery with the phone off and don't let it charging for a long time can solve the problem.
I'll give it a try.
I have it stock and rooted, no alternative rom instaled.

As I said, there is no such thing as battery calibration.
Also, there is no such thing as too long charging. Charging is stopped via specific onboard circuit, if battery is full so there is no chance of overcharging.

Overheat problem exists in 62 too.What he can do is update over the air (OTA) to 62 to maintain root.

yes i know the overheat is on 62 but if you fix it on 42 then upgrade to 62 you will not face this problem

I don't know if changes remain after flashing rom but there is no need to loose root since it's not necessary to unroot for updating.That way he can run the script again if he faces the problem again.
I tried just one time.
I let the phone die with no battery and fully charged it with power off.
Now it's ok again.
Give it a try.

Dear all,
I found a solution for this problem, I hope it will be useful for people that are facing it
after my battery was totally discharged and the phone shut down, I removed the battery ... waited for a while .. then inserted it again ... powered on the phone with charger cabled plugged .. then the phone started to charge normally again 1% 2% 3% ..etc and when it was fully charged I unplugged the charger, it drained normally to 1%
thank you all for your tips.

I have this same problem and i get consistent shut downs at 72% then 53% and every few minutes of usage afterward however this is on my Xperia Play! So perhaps this is a similar issue, I've been needing to solve this for a long time and hope this works! I'll try it asap but I can never seem to fully drain my battery! So I'll just leave the machine for a week and see if it drains! (crosses fingers + Knocks on wood)
