Charging/Battery - MDA, XDA, 1010 General

do you need a battery to turn on a wallaby? i have one and dont want to buy both a battery and a charger to see if it even works.

Well it doesnt run on solar power so i am pretty confident that you would need a battery but if the battery is dead you will need a charger to obviously, charge it. A charger costs £5 in the uk so i cant see it costing you much to try

You misunderstood. I have neither a battery or a charger. i want to know if you can power it on with just a charger. or do i need both the battery and charger just to get it ON?

it works without a battery.

The battery in the wallaby is inside the case, so if you have no battery who took it out and why? But as the previous post states you can use the wallaby without a battery.

it came dissassembled, missing the battery and antenna. and it looks like someones done some wiring in it, but the screen isnt broken from what i can tell. so if its tits up, anyone who needs a screen or parts i probably got em.

[Q] X10 Slow Battery Charging. Help please!

Hello. Today I bought an Xperia X10 from a SH store. Anyway the phone came in great conditions and at a great price. The boy from there gave me the phone and charger + USB cable. All things good till I start charging it. I should mention that when I got the phone it was at aprox. 60% and after using intensively (like when you just buy a phone) it was, after 5 h, at 22%.
Let's get to the problem: I plug the phone with the charger to socket and let it charge. After 3h it went from 22% to 52% . I mean this is really impossible to understand.
My question is how can I find what is wrong. Now I'm wondering if the charger or the USB cable or the Battery is not original.
On the charger there is written SonyEricsson, so I guess it is original. I'll try tomorrow to search for it's S/N on the net. The Output Voltage is 5V and 700mA, which I saw that is normal for an original charger.
The USB cable looks kind of fishy to me.
The battery seems original.
So what could it be wrong and how can I find it out? Any thoughts, beside what I've asked, about this kind of problem are well appreciated.
Thank you.
That's odd considering the current that was flowing to your battery. Try turning off your phone and charging it to 100%. Maybe It needs some adjusting. Also i suggest rooting your phone, no problems with battery at all with the ROMS that are out
Thank you for your fast response. I'll try to charge it to full when it is powered off to see if time differs.
When do you mean "no battery problems with available ROM's" do you mean no charging problems?
yes i mean that
The only reasons u could have a reduction of current is if heat is an issue or if your phone is in heavy use. Also if the charger is faulty of course. So check the temperature while charging and try diabling wifi and any data u have going on the phone. That should help.

Thank you for your response. While I left the phone charging there was nothing running at all. Also I didn't notice the phone heating too much.
I went to the guy from who I bought the phone, and he said that he will order an original charger at no cost for me. So I think I'll wait for that one and see how it works.
But out of curiosity: could it also be the cable that is limiting the power? The cable is not original.

Yes, a faulty cable can't charge the phone properly.
Wait and see how it goes with the new charger!
Did you plug it in staight after you used it? My phone seems to drain when it is at around 45 degrees even though it doesnt feel hot. Let it cool by turning it off for 10 minutes or so and try again.
Sent from my X10i using XDA App
Everything is fine now with the new charger which looks more than original and the USB Cable, also original. (The charge time is ~ 2-3h - empty -> full)
Thank you all for your help.

sgs2 wont boot up, start up

hi, my battery was really low than my phone turned off. i went home to charge but no charging sign. tried to charge it for 1 hour nothing happend. did my phone just died? or can i do somthing to get it back to work?
also i drained it 3 times the past 3 days, could i have broken the battery becouse of this?
try plugging the charger in with the battery out, and fit the battery after and see if it starts to charge? maybe leave it connected overnight or try another battery if possible.

I'm not an expert, so double check the information I'm giving you, as it might be wrong.
Have you tried to use a USB jig to revive the phone? You can buy one on eBay for €5. Hopefully it will solve the problem.
Otherwise, I don't think that it should be the case, but it is reported that SSD drives can be completely erased when they suffer a subtle power cut. In this case, there is no damage other than the complete wipe of all information on the memory. As far as I'm concern, the phone's memory is quite similar to SSD and other flash memories, therefore it would be a possibility, although it is not likely.
Should it be the case, it's better to seek Samsung Service Centre's help. Running out of battery should never damage the phone, therefore, if you have warranty it should be covered.
also i noticed that after a few hours of trying to charge it the battery feels really colld. could this mean the battery is dead?

normally when you charge a battery it heats up a litle. mine stays really cold
Have you tried another charger, or charginging with the usb lead? Soundlike the charger could be duff.

hi any chance did u solve your problem?
i am having the same problem my voltage on the battery drops down to 0 so it does not charge or power on when connected to a charger.
i had to shock the battery with 5v dc till i got the voltage upto 3.2v than put back into phone than on charge but it still drains out completely. any help on how u solved your problem?

Phone doesn't hold a proper charge.

I've been having issues with my phone charging. Took it to Telus and I got a new one. Problem kept occurring so I got the battery replaced as well. Despite basically getting a new phone I'm still having issues. Basically say I'll have 14% battery, I plug it in overnight and come back and it's 34%. So it charges 20% in 7 or 8 hours in the wall charger. I'll then turn it off and pop out the battery, put it back in, turn it on and I'll have 60%. Within a few minutes I'll have 50%. After an hour of use or so it'll beep saying I have 15% battery. I once again pop out the battery and then it'll say I have 40%. I don't even remember the last time I've ever got over an 80% charge or even a 100% charge. I'm lost for ideas at how to fix this.
I'm running ICS S-On, but rooted.
Thanks.
PS The picture I've attached shows what I was talking about. When it was at the bottom red when my phone died saying it had over 20% battery I plugged it in and left it charging for about 14 hours to find it at under 30%.
Sell it and get a better phone
You probably are flashing something wrong or have a rogue app... but there are better phones and its the "black friday" time of year. Just get a better phone.

Have you tried using a different USB cable and/or adapter? Either or both could be faulty.
Give Better Battery Stats a try, and see if it can point out some apps that are running that you were unaware of.
Free app provided here:

Alternatively, based on what you're saying, you might need to re-train your battery stats. Since you used a new phone with a possible bad battery, when your phone depleted itself on that bad battery, that might have trained the battery stats improperly. Retrain your battery stats and see if that will help you out.
Instructions on that are provided here:

—Edit—
I just re-read OP and noticed you advised it NEVER hits 100% charge - Few more things to try:
Firstly, try shutting phone off and charging it OFF overnight, as that might charge it faster.
Secondly, if that fixed the issue, try a different phone charger. Either your USB cord or the USB adaptor (or both) might be bad and not supplying sufficient power.
Thirdly, if that didn’t work, try a different wall outlet – I have run into a few wall outlets that don’t supply sufficient enough power to charge a device.
Finally, if everything I advised fails …… get a new phone. LOL I’d suggest a new battery, but you already did that. If you still have your old one, try the steps I suggested with that battery as well.
Yeah, you could try a different battery or charger. Make the the battery is genuine OEM and new just to be sure, and/or try getting that T-Mobile branded micro-usb charger that outputs 1,000 mAh.

Can you use phone with charging but no battery?

Hi, recently my rn3 pro stopped charging today and i'm trying to figure out if it's the charging connections or the battery itself.
Therefore, if i disconnect the battery, should the phone turn on if i plug it to the charger? I mean there is a direct connection between the charging port and the motherboard, then from the motherboard the battery takes current and charges, so i guess the answer is yes, but i want someone who might have dealed with this to confirm or deny this idea. Thanks!!
In case anyone confronting with this, yes you can, so if your phone doesnt turn on without the battery if plugged then it's the charging pcb that you should replace and not the battery necessarily

If I understood correctly the device can be used without a battery if it is plugged in? The original battery still provides decent backup. So if the above is true I won't bother to replace it with original battery which is still available but can go permanently OOS at any time.

Redmi Note 9S weird Battery Issue

Hello, My phone problem is, whenever i charged my phone to any certain percentage like 80%, 90%, 100%, and unplugged the charger and using the phone, first 5-10 minutes its consume 5-6% battery and first 1 hour of using its consume 10-12%.
This problem happening to all roms including stock rom
So it's not your 'roms'.
Tell me about your fone, how old, and what type of battery?
Does the fone heat up at all when it's draining?
Is there an extra slight BULGE at the back of fone?
I know some charger's, like the iphone chargers, can and do lose their amperage, it's how they sell more charger's, by providing the volts but not the required amps, or in this case, milliamps.
Let me know, and I'll try to help quick as

My phone is 11 months old, and the battery type is Li-ion battery
no heat up while charging and discharging
cant sure is the phone slight BULGE at the back of fone?
By bulge, I mean, does it feel slightly fatter? Bigger? Swollen? can you take battery out, if so, is it neat and tidy, as in, lay battery on a flat surface, it should be flush with where you place it. If it's flat, turn it over, is it still flat?
Have you had any recent updates?

no its not slightly fatter and my phone has glass back panel.....yeah got new updates,but the problem is on every roms
but some custom kernel like etherious and agni kernel...the battery draining normally
So if your battery was getting fat, it would be time to replace it, but due to glass back, you cant tell.
Do you standard charge, or turbo charge?
Back in the 80's, I learnt a fantastic trick, read:
Batteries develop 'memory'. They remember how long they were charged for, in that they kind of copy the previous charge, and dont go further than where the previous charge was halted. Meaning if I'm in a hurry, and pull out fone at 60% charge, next time I plug it in, it MAY see the 60% previously disconnected, as full charge.
For instance, I buy a new battery, when I get it, I dont know how long it sat on the shelf for, as it's charge slowly dissapaited through non-use (yes this happens) while sitting on shelf. So when I get the battery, the first thing I do, is place an electrolytic capacitor (valued around double the voltage of the battery) and place negative of capacitor to negative and positive to positive on battery, the idea being to drain it completely. Once I get no power from battery, I then charge it for 24 hours.
This erases the 'memory' the battery develop's, making it like new from factory. The above is the 80's version of recycling a car battery. But you cant drain the battery, being sealed in your f'n, so try the following:
Grab a usb adapter, say a 4 port (mines a 7 port), and plug your powered on f'n into it, whilst filling the other ports with any other usb devices, the more power they need, the quicker you drain your fone., being the objective.
Do not plug the usb port itself into ANYTHING, and do NOT apply power to the hub.
Leave until nothing lights up plugged into the hub (have a thingy with lights plugged in to see the power drain).
Look for a 3.5mA usb charger, the type used for tablets, the amazon fire tablets charger is ideal for this. Once you have completely drained battery and know nothing else works cause your fone cant supply the other devices any power, plug your f'n into the 3.5 mA (milli-amp) charger, and charge for 48 hours.
This is the electronics engineering method of renewing a battery.
My scource is an old '80's magazine, co-incidently, I'm in same edition called CB magazine, the first ever printed version of how to make a battery like new. I hope this works, cause I dont know the actual fone, but if you do this, you'll have the added advantage of knowing you just 'made' a new battery, and learnt not to buy sealed fones where you cant release the battery to swap it.
As I say, if it's a hardware problem, you'll know after this.
Edit: I know apple mess with the charging cycle to make people buy new iphones, which they do in updates. Your problem MAY actually be this.
Good luck!

So in short You tell me to do that is, i have to connect a usb hub to my phone and discharging all the battery. then i have to charge my phone at least 48 hours/2 days?
Yup. If you take your time, and it's not hardware or update related, you'll be glad you did. At the very least, you make your battery brand new for sure.
Whilst googling, I found some saying some optimisation service wont stop, but hey, it's now down to you to help yourself

don't take me wrong......so the methods u told, really improved li-ion batteries..
and also i dont have any 3.5 ma charger....can i charge my phone on pc usb port
and when charging 48 hours, do i have to turn on the phone or charging with switched off

Yeah it works with EVERY battery made by man, unless it really is DEAD, like no acid to react to the li-ion, shame we cant add water like the car batteries of that time to prolong the battery life lol, back then was poor days, lots of handy finds were found...
I would not recommend the pc/laptop method, because I'm pretty sure those usb ports only provide 50 ma (a quarter of 2.0 mA, note the small ma compared with the 2.0 mA)
Power to pc/laptop end user style is 2.0mA devided by amount of ports.
Any single charger rated 2.5mA or above is what you want, so I use 3.5 mA.
Check old big phone chargers, look at the plug, go for more power than your actual fone charger, which I must ask, is rated at how many mA? I predict 2000ma (2.0mA)
The time (2 days) is to FORCE more power into the previous 'rememberd' memory, literally blowing it's mind lol. After this, you use your standard charger, this is only to fix BATTERY, so then we know if it's hardware or software, cause you did the work and patted yourself on the back lol
Edit: keep fone off while charging, just use another old one or borrow one till the charge is complete. By cheating you only cheat yourself lol. By doing, you WIN.

my phone charger is 18watt fast charger....than how many ma it has....and how many watts in 3.5ma charger??
Glad you asked. Your charger is a 2.3 AMP or 2.300mA like I said, try a larger charger
Look at charger till you get what I'm saying re: ma, mA or Amps (A)
2.0 AMP is 2000mA
To make it easy for you. 2.0 ma (how it's sometimes written) is = to 2000mA or 2.0 AMPS, but do NOT make the mistake of using 2000 AMPS lol, I'll hear you from here...
Electronics is defo not software and I forget sometimes i'm dealing in milliamps and amps, etc rather than megawatss from my radios lol
So you will look for a plug that MAY show EITHER 2000mA or or 2.0 AMPS. The old way to write milliamps were once similar, so ma was made mA to show amps. Keep my age in mind lol
