For some reason, every couple of days when I plug my phone in to charge the battery overnight I end up getting an alert (about 4 in the morning!) to change the battery because mine is dead, along with the back up battery, and then the phone shuts off within about a minute. Luckily I have another battery, which I then put in, and then put the dead battery in the "back up battery" slot in the cradle to charge, which it does. I don't know why this happens but it is very frustrating. I am afraid of this happening on a trip out of town where I won't have the ability to use my cradle, unless I bring it which is a big hassle. I don't know what to do.
This IS vexing. By the fact that it charges the extra battery - we know that the power transformer is connected. Since the device does not seem to be charging (possibly even discharging?) - it seems that either the connector on the charging base or the connector on the device itself are bad.
Have you used the power dongle connected to the power transformer to attempt to charge the device? This would tell you if it's the charging base or the device. If it charges outside of the base, it's the base - if not, it's the device.
Best of luck!
How are you charging the battery - from mains power or through the USB?
I had a situation where I was only using USB power to the cradle and although this worked most of the time, I noticed that if the battery was already low (<50%) then the battery seemed to discharge rather than charge.
So the trigger in your case may be the amount of charge left in the battery before you start re-charging it.
I think other people have reported similar discharging situations, so some other ideas might emerge from a search of other threads.
My battery went flat and I can't find my mains charger, so I connected it to my laptop using the usb cable, with the intention of recharging it. But it doesn't seem to be charging and I can't turn it on at all. Is that normal? Will it only recharge from a mains charger when the battery's dead? Finally, is it safe to by any odd charger off ebay etc.?
I do not know if that is normal or not. However with regards to charging, I have used a Motorola charger with USB connection successfully in the car and from the mains.
If it is all the way dead, you have to charge with original charger. USB charge will not work. Nor will a Motorola charger work. I think that as long as the charger is 5volts, you should be okay. My Motorola charger is like 3v or something.
Thanks
I had the same problem. It does not charge in the beginning, however, if you leave it connected to USB, it will start charging in an hour or so. damn long, but it's better than nothing...
Tried to keep it connected via usb for a few hours, no luck, guess I'll just have to wait till I've bought another mains charger. There seem to be plenty of cheaper ones on ebay etc., is it safe to buy any usb charger?
This happened to me, and I nearly had a heart-attack until I came to these forums for a solution. Apparently, the phone has to be on for the charger (mains or usb) to actually charge the phone. This is because the operating system of the phone controls the charging of the phone. If the battery is completely dead, the operating system cannot control the charging, and so no matter what kind of charger you use, and no matter how long you leave it plugged in, you won't be able to charge the battery.
The only way to get it to work is to get a bit of charge into the battery directly - not through the phone. In other words, you need to jump start the battery (almost like you would jump start a car's battery). What I did was take the battery to a phone repair shop, and asked them to boost the battery using boosting equipment. Their battery testing equipment will be able to tell you when there's sufficient charge to get it going. Then turn on the phone and plug in the charger immediately once it's booted up (in other words, when the operating system can kick in and start controlling the charging process).
Hope this helps.
PS, there's a post on this forum somewhere on how to do-it-yourself, but in the long run, I found my way to be the easier way.
PPS. Once your phone is back up and running, never let the battery run down completely.
Same happens to Motorola V3.
It is ridiculous design flaw.
This is really annoying, I was hoping to sort this out with a new charger (in the post now) but looks like I'm going to have to go to a t-mobile shop. Will they definitely have something to charge the battery a bit, or should I start looking into buying something to charge the battery at home?
Yes you need the main charger.
I was using my other phones charger(motorola) with my cingular 8125 and battery is completly empty it doesn't charge it.
Didn't wait for a hour but if that works.It's good i love my wizard
motorola V3 chargers do work. used the missus' when battery ws completely dead. interestingly, doesnt work the other way around...... :?:
help with my dead battery

Could you direct me to that post on how to charge a dead battery - I have searched but can't find it. This is a really annoying problem - does anyone know of a commercially available battery charger which doesn't need the phone OS (the battery looks pretty standard to me).
Many thanks

Hey everyone.
I figure we could chat on what method you prefer on charging your wizard.
Do you charge always by USB?
Do you only use a wall charger?
A combination of both?
And why? Is there a benefit for using a certain method?
I try to always charge with the wall charger.
I use usb at work - when I need to, but find that it is more of a flash charge, that does not last nearly as long as the wall charger.
Just my 2 cents
Really I heard someone saying charging with a USB saturates the chemicals better?
not sure though.
as with any chemical, the longer the "cure" time, the longer it lasts.
My wall charger charges it too quick and it dies quicker. USB seems to last longer. Also, I have been using a wall plug usb adapter for a long time (the kind you stick into the outlet and plug a usb cord into it) I never had an issue. it wasn't untill i used the original wall charger that I started to have some problems (like I bought a brand new battery and brought it in from the cold (winter) pluged it into my phone; kept my phone off and charged it. apparently the batt got so hot that the plastic covering cracked. the stupid thing was that the batt was not room temp... but I'm afraid my wall charger is deffinately retired. I had the old batt for over 2 years, maybe even 3 and so far it has held up pretty well with usb charging.
Still holds up pretty well if I use usb.
Note: on the wiki they say that the Wizard last about 11hrs on a full charge. that is a blatant lie! I have had it last about 2 days (like the nights I didn't go home) the batt never dropped lower than 30% ever!!! untill I flashed it to a different rom
I posted a fix I think works for me on Merlin's Slim rom 6.1 ver2
It consists of registry settings and and a cab file that should adress your power issues. have fun lookins
I like charging with charge
It takes longer time to charge by usb than using wall charegr

i charge it overnight with the wall charger.
however, since i have started to play on it at work, i bought a wind up usb cable, hacked the wires inside to only leave the power connections, and i bring that to work to recharge it on the computer. call me paranoid, but since the tech support guys jump in and mess with the computer remotely i dont want any chance of them digging thru my phone
and if i have to have to charge it in the car, i have an old fm transmitter you can plug a flash drive into and it will play mp3s...so i plug my phone in there instead and viola el cheapo car usb charger
What lasts longer?
Hi, do you have any workaround how to set my Legend to not charge the battery while it is connected to PC's USB port?
When I want only to transfer some files to SD card and plug the device into USB, it starts to charge. It is very important for me because it continuously damages battery if this happens several times only for some minutes. In Windows mobile there is a great option to not charge when device is connected to USB. I hope there is an option to do this also on android.

I'm pretty sure the batteries today doesn't take any harm of this type of charing. Correct me if i'm wrong

Hmm, on the hand way I am pretty sure that it harms the battery ... 1minute chargings are not good for battery...
I am also certain it DOSEN't damage the batteries...
However.. There are several reasons to disable charging when connection to a PC.
For instance, using a USB hub without additional powers, the drain the phone will put on the hub, will make the rest of the stuff connected to it stop working.
Or simply just to preserve the batteries when using a laptop. The batteries on laptop is bad enough as it is, so no need to put more drain on them...

Lithium-based batteries (like those used in basically every single mobile phone now) love to be topped up constantly. In fact, they suffer permanent damage to the lifetime of the battery if they are ever empty. Don't worry about charging them for a few seconds are a few hours, as long as you don't let them go flat.
Lithium batteries will only work best for a few years from the day they are manufactured (not their sale date, by the way). You'll notice if you have an old mobile phone or iPod that they'll start to run low faster and faster the older they get. This is just a consequence of the chemicals they are made of. It's also why some people refuse to buy Lithium-powered devices that don't make it easy to replace the battery (like iPods, for example).
Also, Lithium batteries don't hold their full capacity right away. They have to be charged for 300% of their capacity for them to be running at peak, although you do not need to do this all at once. This is why some devices come with advice that you discharge them completely a few times right at the beginning. I never do this, because as I advised earlier you do not want to let them go flat. Instead, I charge it up to 100%, use the device down to 50%, charge back to 100%, over and over, since each of those charging sessions contributes to the total 300% necessary.
Nickel-Cadmium batteries were the old sort of rechargeable batteries used in other sorts of devices (toys, remote controls, etc). The best care advice for them is to leave them in the charger until they are needed, and use them until they are completely flat before charging again.
Hi all,
Since the Lollipop update my battery life has been pretty terrible, and the device seems to have run much hotter than previously. The battery hit about 16% by 5pm today, so I plugged it in as normal, just as the update claiming to improve standby battery usage popped up, but the phone wouldn't acknowledge the cable being connected. I've tried different cables, different plugs, tried connecting it to my PC etc and nothing. The battery hit 1% and the phone switched off and is now dead.
Since the battery is not removable, I guess a warranty replacement/repair is my only option at this point, with all my stuff lost.
Anyone got any bright ideas?
Try the new update

I can't, the device is dead!
The only solution I see is contact mother Russia and ask for support or a replacement.

You could flash the latest update via download mode (which would save you from the power hog that is Lollipop), but if the device outright refuses to charge, even from the wall outlet which gives you more power than USB, then you are out of luck.
It's always possible that the phone has been somehow damaged, but I do not necessarily believe that.
TLDR: see at bottom of post...
Since the (initial) Lollipop update, I've had pretty terrible battery life, too. I do happen to have a couple of games that exert a great toll on battery life, and what's strange is that I remember, in the pre-Lollipop days, being able to run the game on my Yotaphone plugged to a USB charger and have the bettery recharge, slowly but steadily. Since the update, I've noticed that the phone, plugged to the very same USB charger, would continue to drain the battery instead of charging while I played the game.
The funny thing is that I decided to install the game on an Android tablet so that I coud keep playing while making sure that the phone's battery would get topped off when I'd leave my desk, and the tablet (LG G Pad 8.3) has shown the very same behavior (i.e. the battery depleting while playing plugged to the USB charger), so I strongly suspect that it's a Lollipop issue more than a Yotaphone issue.
I've read somewhere that Lollipop, amongst other "features", exhibits a bug where the data connection will not time-out as it should, so the device actually remains with a more or less permanent live data connection, contributing greatly to reduce the battery life. Give that the aforementioned games are online games, I'm more than ready to believe in the existence of such a bug.
TLDR: if the battery dies completely, it can take quite some time for it to reharge enough to power-up the device properly. I'd leave your Yotaphone connected to a USB charger for a whole night, for instance, and see if that helps. Trying another charger (preferably 2 Amp, instead of the normal 0.5 Amp delivered by a USB cable), and/or another USB to micro-USB cable (preferably a short one, the longer it is the less efficient it is, generally), and see if that changes anything.
If that still fails to le the device restart, you're certainly out of luck and should contact Yota for a replacement (it is certainly covered by warranty, new as this phone is).
Hope this helps, let us know if you can bring it back from dead-phones-land!
or maybe some contacts at the usb port are brocken. did you try a qi wireless charger?
