I invested in a spare battery for my N1.. the model number of the battery is identical to that that came with the phone.
The issue I have is that even though the battery works, the N1 displays a question mark in the notification bar, rather than a battery status reading.
I've tried running the battery dead, then recharging fully but it stays as a question mark. Is there anything else I need to do to get the reading to work, or is this a faulty or dodgy battery?
I have an extra battery from google and 2 exras from ebay with wall chargers.. all work fine.. no issues.. return the battery

I purchased an unlocked Treo 750 off ebay the other day, I received it in the mail yesterday. THe battery indicator says 0%full and has the exclamation mark on it. It's been like this since yesterday and I've charged it overnight. I'm sure the battery has charge because if it was at 0 it would have died through the night and I've upgraded it to Windows Mobile 6. I"m trying to put 6.1 on there but the PC way won't let me because it thinks the battery is below 50% and i tried the bypass through the bootloader but it says the file is corrupted after 7%. Anway, anybody know how i can fix this battery indicator problem? I've tried installing other battery utilities but they all read 0%!
I have the same problem
I got a refurb 750 last week at the AT&T service center as a warranty replacement. The first few days I noticed that when the phone was plugged in to charge, sometimes it would go up to 100% and seem to discharge normally. Other times it would appear to discharge really quickly and when I would plug it in the charge % would keep going down. Finally last night it went down to 0% even when it was plugged in and it gave me warnings and finally powered off. I have an extra battery (OEM) and extra charger so I put in a battery that I know was 100% charged and it still showed 0%, but this time it never gave warning notifications and it never turned off. Now the indicator just stays at 0% with either battery whether it is plugged into a charger or not. I did a hard-reset just to see if maybe something I installed is interfering with the indicator but even after that it still shows 0% with either battery. It works fine and I'm guessing it will turn off at some point when the battery actually dies, but this is just
Had the same problem
hi,
The problem is the battery.
I had the same problem with my treo after purchasing it from eBay... (I wonder if it's the same store)
I asked the seller to send another battery and he did, now it's OK.
My advice to you is to contact the seller, if you haven't given him a feedback, don't do it until you get a new battery from him.
Good Luck
yeah, i believe it's the battery also. The battery it came with was a 1600mAh and I found out the phone shipped with a 1200mAh. I ordered my own though...only 8 bux...should be here in a day or two
Solution found!
The solution to my problem was the battery. Like I stated in my previous post....the phone came with a 1600mAh battery when i bought it from ebay. The ATT 750 shipped with a 1200mAh battery and the 1600mAh was made for the 755 and another model i don't recall. Once I placed the 1200mAh battery in the phone, it showed the correct percentage and is charging with the battery light on (which wasn't happening before). So I'm not sure if there is different circuitry in these two batteries that caused the conflict but my problem seems to be solved.
Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.
Sent from my Nexus 7
Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
Hello all,
Ive changed the battery in phones labratory.
The new battery is original lg oem anf seemed
Perfectly fine.
Since I changed it,
The battery precentage is stuck on 17℅
I see the lighning bolt as if though its charging
But the battery precentage doesent change.
When I enter the battery it says not charging.
Do I need to calibrate or the battery is bad?
Please advise.
Thanks
Does the same thing happen when you put back your old battery? If it does, it could be a motherboard connection problem.
I've changed the battery in a few Nexus 5 phones using 3rd party batteries from Aliexpress and I never experienced a situation similar to yours. When I replaced the battery, I put the phone on a wired charger while powered off. I waited until the battery was fully charged booted the phone, and everything seemed fine. It's better months since I changed these batteries and they all seem to be working with a wired and wireless charger.
OK, so I've had my SM-P900 for about year now.
Suddenly just this week I am noticing my battery is draining considerably faster than usual and is also taking longer to charge. I was using a custom rom but have now switched back to the default 5.02 version that I installed via Kies.
So after a year do I really need to purchase a new battery?
I keep most everything off all the time and really haven't changed anything or how I use it in quite a few months so was wondering if I actually have to break down and purchase a new battery already.
Cheers
Read the threat : Flickering screen to see how to adjust the tip of battery cable closer in order to make better contact before replace a new battery, within one year the battery should still be good.
If you see the same thing with new battery, probably the battery connector has cracked solder joints and needs to be re soldered, common problem of Samsung tablets, not just only this model.
Lithium-Ion batteries generally last between 300-500 full charge cycles before they start losing power. A year is.. way too soon.
Does it also take longer to charge when the device is turned off completely?
In general a drain increase is caused by a software issue, mobile data or a bug. (or heat/cold.) (The difference between mobile data on and off with a 4G connection is 100-0% in deep sleep in 2 days with LTE, and 80 days in airplane mode.)
Signs of a dying battery include random discharges (it suddenly loses 30-70%, it's at 100 when you unplug and suddenly drops to 30%, or it's dead, you plug it in and turn it back on and it suddenly has 50% charge), random reboots and the device just not turning on at all for no apparent reason.
While it'll loose capacity eventually, that usually doesn't negatively affect the charging speed. (If anything it charges faster because it reaches 100% sooner.)
So assuming that I have a dead battery, is there a good replacement battery out there?
I have tried replacement batteries in the past and have found only subpar batteries on the market.
I bought a new battery on Amazon : 26$
This one is an original battery so at this price you should order one.
And about flickering issue, yes you should resolder connectors or changing the battery might solve this issue too (it worked for me)
Hello,
I have bought an replacement OnePlus battery (the red ones) it looked identical to original one, the only difference was that it had an extra sticker hologram like. The battery was replaced at a service center (after I have ordered it my self, it also comes with 1year warranty).
The issue started the first time I changed the battery. It came charged at first to 55%, I used it until like 35% and then I left it to charge. Charging stopped at 90%. Accubattey measures a capacity of 3050 mah. However the voltage was at 4.280V and at this point it will not accept any more current (charging current drops to 0mA).
When normally charging it with the original charger it draws the usual 2 ~ 2.1 amps. Then I drained it to 0. Now it charges to 95~97%.
My questions are. Is the voltage correct for stopping the charging ? Should it not go 4.35V?
Do you think that repeted discharge to 0 cycles my fix this issue?
Should I consider using my warranty, for the battery and request a new one? Also on this topic. On the supplyer site it states that 5 cycles should be performed to calibrate the battery.
Did anyone else experienced this?
Thanks
calibrate your battery and see if you could find any change,if not, which rom/kernel are you on?
Well I am running 25 Dec CM 13 by sultan XDA, I did not flash a new ROM after the battery replacement.
What steps would you suggest for calibrating my battery ?
I was thinking of dischargeing it to 0 then trying to start it until I get no response from the device. I mean not even show the boot screen. Then leaving it like this for two hours. And then retry to start it, just to make sure the battery is all the way discharged. Then plug it in and leave it to charge over night and see what happens. And if it's still not 100 repeat until it happens.
Thanks for the reply.
