IPhone 5 :: IOS 7.1 / Battery Drain Random Shut Down

Jul 1, 2014

I have an iPhone 5 running iOS 7.1. Today I left the house at 8:30 am with 100% battery. I had a breakfast meeting and put my phone on the table while we ate and did not use it. By 10:00 my battery was down to 3%. On other occasions, the phone shuts itself down while there's still 30% power, and I have to plug the phone into a charger to get it to restart. When it restarts, it shows >30% battery. I've been struggling with both issues for months (as have numerous friends with iPhone 4, 5 and 5s). I do not believe it is a hardware issue, but rather, an issue with iOS 7, which is when the problems began for me. My old iPhone 4 running iOS 6 would go an entire day of heavy use on a single charge (and usually had juice to spare). There is a serious power management problem with iOS 7 and I'm deeply disappointed that Apple hasn't addressed it.

You can conserve battery life by switching off cellular data, closing apps every time you finish using them, and other tricks mentioned by users here, but then the phone doesn't function as advertised and is no longer a smart phone. It is unreliable and essentially useless as a business device. iPhone is advertised has having 10 hours talk time and 10 hours cellular data. It doesn't even come close. I encourage everyone to contact Apple directly to address this problem. Something tells me Steve Jobs never would have let this happen.

BB Curve :: 8530 Random Reboot/Battery Drain

Feb 8, 2011

For about the past two-three weeks, my Curve 8530 has started randomly rebooting - during calls, not during calls - I have not identified a pattern about when. When it comes back up 5-10 minutes later, the battery was always completely drained. I ordered a new battery and fully charged it. Day one with the new battery was uneventful - no random reboots, no loss of all battery charge after one 15 minute phone call, although the battery was low by the end of the day.

Today is day two with the new battery and I had another random reboot, however, this time at least my battery wasn't drained when it came back up. What causes these random reboots? Is there any way to get them to stop?

I am with Verizon and already did the *228 programming update before the new battery.

Google Nexus 5 :: Random Shut Down And Loss Of Battery

Jan 8, 2016

So, I had my N5 since 2013 and the battery as the updates went around was up and down until Marshmallow came out, it was amazing. Great speed , battery and everything, but i broke my own rule and updated to 6.0.1 as soon as i was able to. Well since then the battery isn't so good, and whenever I use heavy apps (primarily when i try to multitask between them) the phone will black out and will turn back on with a chunk of battery missing or it used to be dead. Again this only started with new update so I cant totally point at the battery being old as the problem, but as a new bug with update. I cleared cache and reset it. I tried to downgrade it but kept saying there was missing images and such.

BB Storm 9500 :: Random Crashes And Battery Drain Upon Boot Up

Jan 25, 2010

A few days ago I was running the VZW official .713 OS. Then, I think I installed the latest BBM. After about 12 hours of that, I started experiencing random crashes triggered by actions (not particular actions). I add a contact, it crashes. I boot back up and add again, it doesn't crash - something like that with various other actions like me locking the phone using the left lock button, or snapping a picture, etc.I didn't attribute this to BBM and so figured to hell with the official OS and installed a hybrid (Yes, I'm aware that it's not a supported OS bla bla, but it started with the official .713 so there is merit to this). And upgraded to the new BBM. Installed apps, etc. Battery was draining by 2-5% every 30-45 minutes. Crashes were happening and I wouldn't know till I had to use the phone again, at which point it starts the boot process.I uninstalled the latest BBM and downgraded to the previous stable 5.0.0.66 and it is still going on.

I'm running out of options here.I checked the event log for the time it crashed and encountered only one fatal error:Any help would be appreciated as I don't know what else to do except for installing the old BBM and no other applications. In which case, no point of the phone. I've been using the phone for the past 2 months with no problems..If someone wants me to email this to someone at RIM, that's fine too as I don't know how else to go to them.

Google Nexus 5 :: Phone Random Shut Off / Battery Drops

Jul 22, 2015

Ever since 5.1.1 rolled out it seems like the battery was draining faster than normal but it was at least usable. Now, my phone will just randomly shut off while i'm in the middle of doing something(so far it has only shut off while i'm using the phone and not while it's idle). When it does shut off it could have between 80% and 100% battery even and then when i turn it back on after it shuts off my battery will be around 15% and will shut off again almost immediately.

If i plug the phone into the charger (with it turned on or off) it will charge to full in less than half an hour so i seriously doubt that the battery is actually draining, but the phone sure thinks it is.

So far to try and fix this i've wiped the cache and also performed a full factory reset and that actually only seemed to make it worse - before the reset this only happened maybe 3 or so times per month...now it's happening 3 or 4 times per day which really makes it unusable. The apps that i'm using when it shuts off are not consistent. It will do it in games, in chrome, in messenger - really anything.

I'm willing to try anything - if I didn't provide enough information about something let me know and i'll be glad to follow up.

Motorola Droid Turbo :: Random Battery Drain Due To Phone And Dialer Apps

Aug 4, 2015

Every once in a while (has happened 2 times in as many weeks) the phone or dialer APP will suck battery and throw off my typical discharge time WITHOUT me ever placing a call (let alone opening the phone interface). For example, as shown in the attached, I'm down almost 70% on just 19 hours and change of use, with just 2.5 hours of screen on time, with the phone app draining 7% without any phone usage. Typically, I can make it 24+ hours with 4+ hours of screen time on that level of battery drain.

Aside from those instances, battery has been great on L. Used to get, typically, about 26 hours before charging at 25%. Now, I consistently get 29+ hours on the same usage.

BB Bold :: Random Input Keys Shut Off?

Nov 10, 2011

Information about my device:Blackberry Bold 9780Platform: 6.6.0.241App Version: 6.0.0.666Carrier: Rogers CommunicationsSome of you might call this "randomly shut off" but its not! the device is still running...The issue is that at a random time blackberry keys will stop working eg. All buttons on the device including lock/unlock key while this is happend the blackberry screen is in sleep mode or whatever you call it when device isn't in use but ppl think it shut off automatically. During this time you can receive calls, bbm, nd text and all that you just won't be able to answer the call, reply to bbm, and so on... P.s screen turns on if u receive a call obviously.The only fix for this is to pull out the battery so it reboots fully this is only temporary may happen again.All you other people are just giving RIM false information like "blackberry just auto shut off" without even bothering to look into it your first goto place are these forums..

Motorola Motoactv :: Coach Won't Shut Up But At Least MP3 Random Works

Jun 2, 2012

While running 7.2 software. Interesting new bug this week. When running, I decided to pick up the pace. Hooray for me, I set a personal best since last resetting the Motoactv. The coach comes on and tells me "New personal best... [and the time]." Then 15 seconds later, the coach comes on against, and tells me "New personal best... [and the time -2 seconds]." It did this about 10 more times, every 15 seconds. By the end, you would think I was setting world records it thought I was going so fast. I had to figure out how to turn off the coaching mid-workout, which was fairly difficult while running.

I am running a half-marathon tomorrow. I would have liked to use the coaching feature, but will not try it again for a while. Hopefully a hard reset and the new 7.3 software cured that bug since there was no bug fix list with the new release.

Motorola Xoom :: Random App Shut Down And Forced Closures?

Dec 7, 2011

I recently purchased a XFE and have been having multiple issues with apps and the browser randomly shutting down. There doesn't seem to be any reason for this. The battery is not low, I'm not doing the same thing each time, I don't have multiple tabs open (although I have heard this tablet is wonderful at multi tasking). Also at random times I will have an app open and it will pop up with a message about force closing. This has happened way to often for me to continue to tolerate this.

Did I get a bad tablet perhaps? I want to keep this tablet? The rep was at best buy when I was looking at these and convinced me it was the lastest and greatest, however other tablets do not seem to have this issue .

IPhone :: 4 Battery / How Much Does Wi-Fi Drain?

Jul 28, 2010

Previous smart phones I owned turned wifi off when the screen went dead. So essentially wifi didn't really drain any battery and wifi was easier on the battery then 3g when actively pulling down data.

So now I am on a 2gb plan (previously on unlimited) and sensitive to this I keep my wifi on all the times to use my home connection when possible.My battery however is barely getting through a full day. My wife was getting solid days but she had wifi off.Do you think that this is effecting it? I use my phone quite a bit throughout the day.

IPhone :: 4s - Battery Drain With 5.1.1 OS

May 24, 2012

My iPhone 4S had been working great, but after upgrading to 5.1.1 OS it is draining the battery by the afternoon every day without any or very little use. I rely on my phone for business and it can't even make it through a work day! It is draining about 4 times faster than normal. I found a post referencing to 'Reset All Settings' which I tried yesterday, but it still is draining fast. I tried resetting, rebooting, shutting down all apps, but nothing helps.

Google Nexus 5 :: Battery Monitor Do Not Add Up To Total Battery Drain?

Nov 29, 2015

Nexus 5, 16GB, MRA58N (stock, not rooted). Sometimes the power percentages shown for each process in the battery monitor do not add up to the total battery drain? I am finding that sometimes they add up to within 1% of the total shown.... and sometimes they are WAY off with as much as 30% of the displayed battery drain unaccounted for. Since I don''t have access to the battery terminals, I can't determine independently whether the percentages shown are simply inaccurate, or whether there are missing processes (ie., processes not shown at all in the battery monitor).

I plugged in my ip4 last night a couple hours before going to bed, and noticed that it was up to 100% when I went to bed. I woke up and, still plugged in, was at 97%...?Is this normal by any means?

IPhone :: 4 IOS 5.1.1 Battery Drain Partially?

May 14, 2012

A week ago I realised that my phone was heating up rapidly and my battery was being drained alarmingly fast before days end. I used to go a whole day and would only hit 50% battery use. After some research, reading and testing of my own, I can say with some certainty that after turning off the push notification and location services on my phone battery life has dramatically improved returning to pre update performance and the overheating has ceased.

IPhone :: 4s - New - Battery Drain And App Crashing

Jul 4, 2012

I have recently bought a new iphone 4s- 16gb. Updated it to 5.1.1 version.

The iphone has major battery issues. I charged one night and morning it was drained. It was only on wifi.

Also, while on wifi - the battery drain is too much. The standby time and the usage time are generally same.

- Location was off
-Bluetooth off
- wifi on
- Emails on

The drain is very fast. Next - the apps like facebook, contacts, watsapp etc carshes quite frequently.

I installed an app called 'Battery Doctor', in the stats i found that the CPU usage is very high even wiht only 1 app running. similar is the case for RAM usage.
