i'm trying to sort out the battery on an archos cobalt 80. at the moment it has the latest stock firmware available from the UK archos support page. i restored it to factory settings from the recovery menu earlier today.
i'm fairly sure the battery isn't dying, because just a few days ago i had it working all day from a single charge, although now it will barely hold a charge at all. thing is, it doesn't seem to be possible to fully power it off, which is necessary to properly calibrate it. it apparently should be possible to switch it all the way off then plug it in so as a battery charging animation appears on the screen, but this thing just seems to go onto some sort of standby mode. if i try to charge it with it switched off, the damn thing switches itself back on again. i've read that it should be possible to power it off properly from the recovery menu, but the option simply isn't there, only reboot. it says that it's recovery system v 4.00.
is there an older/newer recovery image for this tablet that i can flash that will allow me to properly switch it off, or could i do it by installing CWM? or is there a secret button combo that will properly power it down?

So it seems that no matter what i do regardless of rom, kernel, bootloader version if I press the power button while my gtablet is awake, it will just shut off- maybe twice now it has successfully unlocked for me and came back to life.
The other night i did a test, with 100% battery set the brightness to its lowest setting using the power manger widget (this seems to be 30 out of 255 btw)
Idling while I slept (screen on, sitting at the home screen) it ran 10 hours and still had 16% left.
Obviously the screen still remains as the key battery drainer, so my question is- is there a way to turn the screen off but keep the cpu running? Perhaps even just kill the back light completely- and upon volume button press or maybe a certain swipe gesture on the screen, the back light could be re enabled.
Ive tried a few apps, none of which have functionality quite like this- I was wondering about perhaps a script we could run via terminal (that maybe could be tied to a shortcut on the homescreen..?)
Thanks!
the sleep of death is my #1 gripe with the deivce.
what i am more interested in is why this happens. I would imagine this doesnt happen in stock form, so it must be an issue with rooting it.
Nope
No it happend in its stock form too... even with the 1.0 fw that i started with...
Went for the update to 1.1 bl and 1.2 bl
I really haven't been able to determine the issue and ive tried every rom between 1.1 and 1.2 ... (at least all the obvious ones on the forums here...)
Not sure what to do other than suck it up and just find something that can kill the screen.
Hi, so sorry for the vague thread title, but really, there's no other way to describe it. So here's what happened.
For the past few weeks (or month), my Xperia Ray has had a problem of switching on after it was put into standby mode, i.e. after i pressed the lock button. The screen would light up, however would remain blank. So all I would get is a bright black screen.
I could have lived with this for a few more months (until Xperia Z gets released in my country D: ) however this problem started getting worse. At first, after pressing the home button, the volume rockers and/or the lock button for about 20 times, the screen would turn on (finally). Despite it giving me that bright black screen, i could still operate the screen. I could still try to unlock it because of the haptic feedback on my lockscreen. I could still change music tracks on my music widget on my lockscreen. In short, the screen worked perfectly, only that it kinda wouldn't show. However, for the past week, the only way to turn it back on would be to do a battery pull and switch on the phone again. And it recently developed a problem of giving me that bright black screen again when I switch it on, causing me to do about 5 battery pulls before being able to actually use my phone again.
I did get fed up with this problem, being a heavy user of my phone. Therefore, today I decided to try to do a factory reset of my phone, intending to wipe the dalvik cache + clear all user data, thinking it might help my bright black screen problem. However, I found that I couldn't boot into recovery because all my phone would do was to give me that bright black screen again! So after many battery pulls, I managed to boot up my phone normally and do a factory reset under the backup & restore tab in settings. Of course, the phone tried to reboot itself, but of course, just gave me the bright black screen.
I kinda gave up at this point, and did many battery pulls and boots, however, all I got was either
1. the terrible bright black screen
or less frequently
2. the free xperia project logo then the terrible bright black screen.
I did get very fed up, so I plugged it into a wall socket to charge it. However, since about an hour or two ago, I realised it may be on bootloop. When I plug it into a wall socket, the free xperia project logo shows up and then an even brighter black screen shows up for about 3-5 minutes, then those two repeat endlessly. The notification light doesn't show that it's charging at all.
Okay here's background info on my phone.
- Is rooted
- Bootloader is unlocked
- CM 9.1 is installed
- Was running GO Launcher (if that helps)
- had a custom boot animation
- I think i deleted an apk for the google start up configuration thing...the one that asks if you have any google accounts you want to connect when you switch on your phone for the first time. I'll search up the correct apk name if you need it.
- Is about a year old (got it last early April)
- is a Sony Ericsson Xperia Ray (in case you didn't notice haha)
- battery level was about 20%+ when I did a factory reset (terrible of me I know)
- I have tried to caliberate the battery a few months ago
That's all the background info I can think you need. Please do let me know if you need any other info. If you need the logcat text of what happens when I hit the lock button at the top of my phone and the phone gives me the bright black screen (the early stages of this problem), let me know and I'll dig it up. I think I've bricked it, but I can't boot it into recovery so I can't do anything. And I did all I could google for the bright black screen problem which I won't tire you by specifying here. Please do help me. It seems as if the worst of evils has befallen my phone. Now I'm stuck here with my phone crazily on bootloop beside me. Please please do help.
Flash stock rom
Just try flashing a stock rom with Flashtool. If the problem persists, then it could be a hardware problem. Flashing a stock ftf takes care of all software issues. Get the stock ics FTF file and place it in firmwares folder of flashtool. Start flashtool and select flash mode. Then choose your ftf and press ok. Then wait until it prompts you to connect your phone. Then, just turn off your phone, while holding the power button down attach the USB cable. The LED notification should turn green and wait until it finishes flashing.
flash extended stock kernel and then the stock ftf firmware file...
hit thanks if i helped u
I have the same problem on my Xperia Mini (ST15i) I use Pureness rom and Mesa Kernel... ((

Hi, if your phone can still be switched on and hasn't progressed so far in being destroyed, you could try downloading the Disable Auto Brightness app for Xperia phones from the Play Store. I've read somewhere that the screen might not turn on because of the auto brightness. I'm not sure if it actually helps, but perhaps my phone would have died faster without it. I've read of people changing their battery, doing battery calibrations or changing their screen to fix the problem. But before you change the hardware, I suggest that you check the hardware first. If the Disable Auto Brightness doesn't work, do a Nandroid backup and store the backup somewhere safe. Then flash the stock firmware to your phone and try to get it to switch on. Do flash the firmware before your phone runs out of battery because you never know, your phone may decide to refuse to charge your battery anytime. Then try to switch it on. If your phone goes into a bootloop (like mine now) really consider getting a new phone or sending it for repair or try all day to fix it if you use your phone alot. I'm still trying to fix mine.
I flashed the original firmware for my phone, tried to turn it on, was very happy when I saw the original Xperia logo, but then I realised it was on bootloop. When I tried to charge it, it immediately turns on and goes into bootloop again. Logcat doesn't detect my phone, so I can't obtain the logcat of what's happening. I haven't tried to replace the battery of my phone because I couldn't find a supplier. But I'll go on trying to fix my phone until the day that it really breaks down. Good luck with yours and keep us posted.

Hello,
I have a Samsung SM-J120M that's rooted with SuperSU and is on stock 5.1.1. The phone feels warmer than usual just above the Home button.
I open up CPU-Z and it tells me thermal_zone0 reaches temperatures up to 49°C (120° F), the battery never goes higher than 32° C (89.6° F), the CPU overheats only when it's not in standby. Oh, and all this is happening while it's 18°C outside my house.
This problem started four days ago, the same day I installed Nova Launcher. So I switched back to TouchWiz, yet the problem persists even after freezing Nova in ROM Toolbox Lite.
I wanted to restart in Safe Mode to see if I could solve the problem that way, but when I long press Power Off, I get no prompt. Even pressing Volume Down at the title screen didn't work (the screen hangs on there Samsung logo). I've wiped the cache partition. My microSD card is fine.
I don't know what else could be causing this.
If you could help me that'd be really great because this phone is very useful to me.
Thanks in advance.

Try this for safe mode
With the device powered on, press and hold the Power button (located on the right edge) until the Phone options prompt appears then release.
Tap and hold Power off until the Reboot to Safe Mode prompt appears then release.
Tap Restart.
Note The restart process may take up to 45 seconds to complete.
Note Upon restart, Safe mode appears in the lower-left of the unlock/home screen.
also download from google play store Wakelock Detector [ROOT] .
Charge your phone 100% and then wait until goes low let's say 20% then open this app to see which apps drain your battery and which apps use most the cpu and cause high temp.
Hi all,
I got this Xperia M5 that's been giving out warnings about memory being full and I suppose it finally gave in. It only partially boots after like a full minute of showing you those blue waves. When it 'boots' the screen is black and nothing works, except you can see the status bar with just the battery icon, no-SIM icon and the clock.
Weird thing is when the device is powered off, you can press the power button once and it'll display a large battery indicator which shows the percentage normally-- I've seen this go up from 0 to over 90 something incrementally.
But when it's 'on' the way I just described, the battery is always at 0% with a red ! next to it.
Anyway, when it's in this weird half-life mode, you can actually pull down the notification bar normally, and tap stuff as well. Flashlight works, you can see an actual WiFi list (nothing happens when you connect) etc. When you launch stuff through here though, like settings, it won't open anything. It'll make the sound as if it's launched something but the remainder of the screen will still be black.
Using the dedicated camera button, I can access the camera. It works (sort of), meaning you can see the camera display where the screen used to be black. And it immediately says "system process is not responding," so I'm guessing this is a system issue where it can't load basic stuff like the homescreen?
Whatever you do or don't do, it stops responding after a couple minutes and shuts itself off.
Stuff I've already tried:
- Safe mode (volume down + power), just 'boots normally'
- Recovery mode (volume up + power) done that for over two minutes, does nothing or just 'boots normally'
- Hold down the tiny yellow 'off' button under the SIM/SD cover, did nothing.
- Xperia Companion: PC won't recognize the phone either in that zombie state, or when it's off, so I tried 'device cannot be detected', shut phone down, held down volume down button, connected USB still holding down, waited for a while and viola, nothing happened.
It's factory OS, never messed around with it and I don't know the version (could be 5?).
Any ideas?
Guys at this point all I'm wondering is if anyone ever managed to brick a phone that's as semi-responsive as this one, in the history of bricked android phones anywhere.. I mean how could it be bricked when you can (sort of) boot and even open the camera?
you said it boots in download mode?

No I wouldn't say download, it's weird-- there's the status bar at the top and soft navigation keys at the bottom, but the homescreen in between these is black. I tried tapping this black area to see if stuff is there logically but you just can't see them, but there was no interaction, no sound or anything.
I am able to pull down the status bar to reveal the usual buttons and such, like I mentioned before you can turn on the flashlight, click to see a list of available wifis etc. But you can't access settings through here, I mean you tap settings and the main part of the screen is still black.
The only way to get the screen to work is to open the camera through its dedicated button, where the camera display works normally, you can switch cameras etc. Tried accessing the gallery through here but it didn't work.
I just don't wanna buy a new phone when this one doesn't seem bricked at all. If it like didn't respond at all and nothing appeared on the screen I wouldn't think twice before buying the first phone I see on Google.
im afraid that you have to flash stock rom again if you will boot into download/fastboot mode.but your problem seems strange.what was the last thing you have done before phone stuck like this?

Not my phone but it'd been going on about low memory for a while now. I got the PC to recognize it once in that zombie state, so I'll try that with Companion if I can get it to half-boot again. I'll post updates if anything happens.

Hi there,
I have a problem with my Stratos 2. After letting the battery to drain during sports, I'm not able to start it.
When I put the watch into charger, regular charging interface is visible and the battery charges to the full battery.
but if i try to start the watch (at any point, or after the battery is full) with the upper button, the display lights up, but doesn't actually load any screen at all. other button don't do anything, and if I press the upper button and hold - the display light just turns off.
is there any way of doing "mechanical factory reset" (as Im not able to get to the menu) or is there anything else I can try?
many thanks for any help, it will be very appreciated!
Matej
1. "Stratos 2" does not exist, it was never released (yet).
2. Try to get manually to fastboot mode, look for more info here and on YouTube. If it works correctly and bootloader is unlocked (you can unlock it in this mode as well) then you can try to wipe data/flash a new firmware. But if the watch is still under warranty and it wasn't voided, I would recommend that you get it replaced.
