My Fuze has started to exhibit some very odd battery life behavior. Over the past 10 days or so, I've noticed a pattern of extremely poor battery life every other day. I recharge my phone everyday overnight, but some days the "low battery message" appears only after a few hours. I'll reconnect to a charger to make it through the day and then recharge overnight as is my typical routine. The next day, the battery will last me all day and not drop below 50% before I reconnect the charger before going to bed.
Today the "low battery message" came on only after 4 hours of battery use in which I did not make a single phone call, text, e-mail, etc. Yesterday I used the phone heavier than normal and the battery was going strong well into 11:00 PM.
I'm not sure if this is a battery issue or a phone issue, but I'll be darned if I can figure out what the heck is going on. Any thoughts?
I bet its most likely that the phones battery isn't properly calibrated and is why it doesn't show correct battery drainage. I would just buy a new battery if i was you.
Or load up a new rom to your device which cause the battery to need to be re-calibrated and should drain rather quickly over the first days and then go back to normal.( Note- you should allow battery to drain low normally before a full charge again)
But if your battery is just at its end this is pretty much useless, so either try it at your own risk, or just buy another battery -> Really cheap on ebay from trusted sellers!
This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

i feel like i do this every time i recharge my battery because every time i charge to 100% then turn it off and plug it in, it takes another 5 min to charge to 100 while its off. Literally, every time i bump charge it.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.
The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

The "software" won't ever be off by more than 10%.

Not true with lithium ion batteries. They don't have charge memory.

I was having all kinds of issues with my battery draining too fast. I unplugged at 7:30AM and by 10:30AM it would be at 60%. I tried the bump charge and all that, but then I realized "It's the apps, stupid!" I started running a task killer after I unplugged it, and now I'm making it to noontime and I'm only down to 80%.
TLR: Keep your apps in check, they are what eat your battery.

A few days ago my phone shut off after draining the battery - before it shut off the battery was less than 1%. i let it sit for ten minutes or so then turned it on. - it showed 16%.

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.
I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS
widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

I've a feeling it has less to do with the actual widget and more to do with their constant updating when there is a poor or nonexistant connection.

Don't download the anaimation sub-app. update on the hour (or 2) instead of 15 -30 min.
I would love some advice as a noob here. I've only had my Cappy for a little over 2 weeks. I've done the battery calibrate trick, but still don't see very good battery life. I unplugged from the charger at 100% at 10pm last night and left the phone on all night. Wifi and GPS were turned off. Beautiful Widgets is set to update weather every hour. The phone received 7 sms messages during the night. When the alarm went off at 6:30am I was at 70%. It's 10am now, so it's been off the charger for 12 hours. Here is what I show:
Voice Calls 34%
Cell Standby 23%
Phone Idle 16%
Display 15%
Android System 4%
Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%
antivirus 2%
Battery currently shows 51% left

Would anyone suggest Advanced Task Killer or Juice Defender?
There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

PLEASE DO NOT INSTALL ANY OF THESE BEFORE READING

If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.
I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!
Is the first charge on the Nexus 5 still as important as a few years ago? Or is the N5's Li-Ion battery not as sensitive as Li-Po batteries?
I always used to plug in a new before booting them up, charge the battery completely and then unplug it. When the charge went down to about 5%, I plugged it back in. I always did that two or three times and then - while still trying to do it like that all the time - allowed myself to charge the device for a few minutes only when it was necessary instead of plugging it in and leaving it at home.
Well, on the N5, I didn't manage that - I actually forgot to monitor the battery level yesterday evening before going to bed. This morning, I noticed that the battery had reached 1% during the night and the N5 shut itself down.
Of course, I did now plug it back in, but I wonder if I could have damaged the battery by letting it run down to 1% on the first charging cycle? Or doesn't this matter at all and it will still reach its full capacity after a few charging cycles?
Thanks

I wouldn't worry about it, running a battery to empty is indeed bad but they don't allow you to run it to empty. It is programmed to show 1% and shut down before the battery itself is at 1% to prevent you from damaging it.
Use your phone, when charge is about 20% connect your charger and do not disconect until reaches the 100%.
This is what i have done with mine.
I have reached 2 days standby with about 3 hrs of screen on time.
I have noticed that when i plug my Z5 in to charge overnight, it will charge to full in just a few hours and then remain plugged in for the next ~6 hours until i unplug the phone 'fully charged" in the morning.
My theory is that the phone loses charge (maybe to protect the battery?) when left plugged in at full charge.
I will only get 3 hours SOT max if i leave my phone charging overnight. But if i unplug my Z5 as soon as it is fully charged i get 5 + hours SOT.
Also, often when i plug my phone into charge at 1 or 2 %, it sometimes actually causes my battery to die, before the phone boots again and starts to charge. Does anyone else notice this?
I am using the stock sony UCH 20 charger with came with my Z5.
What do you guys think?
That does sound peculiar. It should be noted that while it is normal for the phone to protect the battery by cycling between 90% and 100% when plugged in (battery gauge doesn't account for this, that's why it appears full all the time), it definitely shouldn't cause a 40% difference in SOT even if you happened to unplug when the battery is at 90 percent.
Yes, you're right. Once the battery is charged to 100%, the phone stops charging and will let the battery drop to around 92% and once it hits 92% it will start charging again to 100%. Even if you unplug the phone when it's showing 100% after charging at night, it might actually be charged to 93% for example. That's why very often people complain that the first 10% of the battery drops very quickly, while in fact it's just the battery meter catching up with the battery charge. This is done to protect the battery and ensure it retains charge after many cycles.
Regardless of that, the difference should not be that huge. For me it's usually extra 30 minutes SOT.
It seems the stock firmware has a load of random wakelocks but I have hope that a soon to come update will fix most of the issues, if you are rooted I suggest that you use greenify or amplify (reqires xposed)
Hi everyone,
I have a Leagoo T5c with a more-or-less 3,000 mAh non-removable battery, and for the past few month, battery life has been somewhat erratic. The phone would go from, say, 50% to 10% battery in no time, and I would get the low battery warning, but at other times it could hold at around 45% for a while before really going down for good.
Last night around 8pm my time, the phone went completely dead while the battery indicator in the task bar said I still had about 65% left.
I tried what's described here and there as battery calibration: I left the phone turned off, patiently waited a couple hours (yes, yes, that long) for the battery to reach 100%, then left the phone off for another hour before turning it on.
In a matter of minutes doing nothing more than checking my Twitter TL, the battery went from 100% to around 85%, and was still there went I tucked in for the night, leaving the phone in Airplane mode as I always do at night.
This morning, I turned Airplane mode off and the battery said it still had 82%, which means minimal drain during the night, with all radio off.
Just a few minutes ago, the phone went completely dead after the low battery warning, and the battery held less than 10% charge.
WiFi is off, cellular reception is very good where I live, and anyway, I don't see how LTE could kill 70% of the battery charge in less than half an hour, even if reception was spotty, which it's not.
I plugged the phone into the charger it came with, put it in Airplane mode again, and it went from 10% to 70% just now in less than 30 minutes.
I know for a fact that fast charge isn't supported on this phone, at least not with the OEM charger, plus it has micro-USB, so I doubt the charger can feed it that much juice in so little time.
The charger itself seems to work fine: It never gets hot while charging, not the Leagoo, nor my old iPhone 6, since I use it for both devices.
So, long story short, is there a way or tool to ***really*** know what state that battery is in? I've tried both DevCheck and CPU-Z, and both say that the battery is in good health, and still retains its nominal capacity of more or less 3,000 mAh, but I have my doubts about that.
I think the battery capacity is reduced somewhat, and I need to know by how much.
Any help and input would be much appreciated!
I must add that I flashed a stock ROM on this phone (yeah, again...) a few days ago, so maybe it's the ART cache being replenished that's causing my battery issues, but still, the problem is so inconsistant that I don't know anything anymore...
I had to flash the stock ROM again after trying (again...) to root the device (successful, but doesn't bring anything of value) and finding it barely responsive.
I'm gonna leave the phone as is, ROM-wise, but my battery is still a matter of concern, because it dies on me at the 60-65% mark more often than not, though two days ago I let it drop to 30% without the phone shutting down.
Like I said, it comes and goes. I really need to know if that battery still retains its nominal capacity or not. Any help in that regard would be most welcome...
