[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Aerobreak:
My girlfriend recently dropped her S4, and now it seems to be stuck in a boot loop. I can boot into recovery and the bootloader, but not the actual operating system. I tried re-flashing the stock firmware using Odin, but that didn't do anything.

She has pictures on the phone that we'd really like to keep if at all possible, so factory reset is a last resort. I've been looking into trying to put CWM on it and make a backup just in case, but I'm not even sure if I can or if that would help.

Additionally, I've tried to pull the files using adb, but I can't get connected to the phone except in sideloader mode, and I can't seem to pull in sideloader mode.

Any assistance would be appreciated.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] audit13:
Is the phone an i337 from att? Does it have a locked bootloader? If the answer is yes to both questions, you can't load twrp or cwm to the phone.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Aerobreak:
It is an I337. I'm not certain if it has a locked bootloader or not, but I'm thinking it probably does because in the bootloader screen, it says:

WRITE PROTECTION: Enable

eMMC BURST MODE enabled​

So that rules out flashing a custom recovery, I guess. Is there any way to make a backup with the stock recovery? Or anything else you can think of that we can try without factory resetting?

Thanks in advance.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] AlaskaLinuxUser:
Two thoughts for you:

1. I know this is a dumb question, but did she save the pics to the internal phone memory or the external sdcard? If she set the camera to save pics to the sdcard, you can pull the sdcard and get your pics from it. I am sure that you already thought of that.

2. You said you flashed the stock ROM with odin, but it didn't do anything. Was it successful in downloading/installing to the phone, but didn't solve the problem, or did it fail to flash? If it did successfully flash, your pics are probably already gone if they were on the internal storage of the phone.

Also, a longshot, but you could try to wipe the cache in recovery mode and see if that fixes your boot loop. This will not wipe your data, but may clear up some of the system cache, if it was somehow corrupted when dropped/stopped/powered off.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Aerobreak:
1. They were on the internal storage.

2. I....totally didn't think of that. It flashed successfully. Great. Well, I guess a factory reset won't hurt as bad as we thought then.

Thanks for the help!

Boot into recovery and look at the second line. This will provide the recovery version. The last 4 characters will help determine the bootloader version.
[Nexus 5X Q&A, Help & Troubleshooting] Moonboots:
Is there any way to remain stock, unrooted and have a quick toggle for the location setting (high accuracy, battery saving, device only, off)?

I keep it on battery saving generally to ensure I can make full use of Google Now but toggle location on for navigation as needed. It's clunky to have to go back in to the menu manually and change it to battery saving every time. Any suggestions?
[Nexus 5X Q&A, Help & Troubleshooting] neu - smurph:
No particularly elegant way.

I do the same as you, but have my authomation app (MacroDroid) show a notification when High Accuracy is set and a press on that notification starts a Macro that uses the Tasker plugin AutoInput to switch back to Battery Saving (MacroDroid can use some Tasker plug-ins). AutoInput allows you to automate various screen touches. So still clunky but allows you to switch back with one press.
[Nexus 5X Q&A, Help & Troubleshooting] redger725:
There is a Settings Widget in stock that will get you there quicker. When you drop the widget onto your screen, it prompts for the setting shortcut type. Select Location when prompted.
[Nexus 5X Q&A, Help & Troubleshooting] Evo_Shift:
If you install "Power Toggles" from the play store you can customize which quick settings buttons appear and would be able to create a toggle to get into the location settings so you could tap that and you would immediately be in the setting menu you want. This doesn't require root. Unfortunately Power Toggles doesn't seem to have the ability to cycle through those settings at all without root. Getting to that settings screen quickly is nice though.

However, If you have root access you can create a "GPS" toggle which would switch your phone between "Battery Saving" and "High Accuracy" and a long press on that toggle could pull up the location settings menu if you wanted to go to "Device Only" mode. For some reason there doesn't seem to be a way to toggle "Device Only" without going to that menu which is why I have the location menu set up as a long press on that GPS toggle. I typically leave it in "Battery Saving" and if I use maps I will toggle it to "High Accuracy".

Hi,

I just bought my Kaiser 4 days ago.

I am using the bluetooth adn an SDHC card.

My problem is, following: the batter goes every day empty! I unplugged from the charger 4hours (I was using the phone for one our), and the batter is on 34%.

Do you have the same problem or my batter is wrong?

tnx:

[Tilt, TyTN II, MDA Vario III General] gogol:
Wow, really fast battery drain.

No, I dont have that fast drain.

Do you use data connection all the time? Wi-fi? 3G?

Backlight? Power off when device is not used ...

Worth to check.
[Tilt, TyTN II, MDA Vario III General] nagyadi:
I switched off the online data connection and the 3G..

I jut pulled off the SDHC card for testing the battery...

:(

I hope it will help..

How often do you charge the battery, and how long do you use the phone per day?
[Tilt, TyTN II, MDA Vario III General] gogol:
It depends ... between 1 or 2 days ... and I usually charge when it is at 30% - 50%, during evening.

And I use 3G for browsing the internet for now and then randomly also MSN/Yahoo chat.

I suggest to hard-reset, and run your phone without any app installed.

Then see the battery drain.
[Tilt, TyTN II, MDA Vario III General] michalopoulosgk:
big source of battery drain for me was the WiFi and the push email.
[Tilt, TyTN II, MDA Vario III General] Bratag:
I have also noticed the battery drains pretty damn fast. Much faster than my wizard it would seem. I am slowly disabling things to see if I can find the source. Otherwise I am calling HTC and getting a new battery.
[Tilt, TyTN II, MDA Vario III General] Pooper:
Are you leaving Bluetooth on? That will drain the battery pretty quick
[Tilt, TyTN II, MDA Vario III General] Bratag:
Nope - no bluetooth - no push email. Its very wierd.

sorry i was referring to the OP :P
[Tilt, TyTN II, MDA Vario III General] nagyadi:
I am using the Spb GPRS Monitor.... Does it need extra battery power?
[Tilt, TyTN II, MDA Vario III General] herpi:
I think that is not correct. Bluetooth hardly has any influence on the battery drain.

You can leave it on for ever.

But do a test yourselve.

1. Load the battery 100 %

2. Set bluetooth on or of and put your baby to sleep for 8 hours.

3. Check the battery situation in the morning, the first time you start using it. You should, in 8 hours, not have lost more that 4 till 5%.

That is with GPRS and no 3G or HSDPA. I did not test that, but...

You will see that a night with, or without, makes hardly any diiference.

But maybe I am wrong.

My personal experience is that using GPRS ( Phone=GSM only) is the most efficient. Especially if you have Messenger on the whole time.

[Tilt, TyTN II, MDA Vario III General] PhilipL:
Hi

When Bluetooth is on the device will not go into standby even if the screen appears dark as Bluetooth needs the OS to be alive to work, so if you have programs loaded that are using CPU cycles the battery will drain quickly as these programs will run continually.

Regards

Phil
[Tilt, TyTN II, MDA Vario III General] herpi:
The only thing that I am saying is that my phone, in 8 hours, with bluetooth on, uses max 4% of battery drain. With blutooth off I see no difference.

The phone is in sleeping mode, so people can call me. What else can I say?

So I cannot say that Bluetooth drains my battery faster. At least not visible to me.

I tested did a long time ago with several systems. the last one, before my Tytn II came was on blootooth its whole life. And now again I see the same at my little kaiser.

Huib

P.s. and then this.

I see as standbye the situation, that I only can switch it back on with sliding the keyboard or the power switch. If other keys do not react, is in't this standbye? The rest of the discussion I prefer to leave to better specialists on this forum

[Tilt, TyTN II, MDA Vario III General] austinsnyc:
For Best battery life you should make a false Push email and set it to check manualy there is info on google about how to do this. thats only if you dont use exchange. Also NO bluetooth yes it does suck lots of juice! Also make sure you dissable the IR connections that also sucks juice. there are also power saving reg tweaks in the registy that you can find in the Wiki :)
[Tilt, TyTN II, MDA Vario III General] RemE:
There is no I/R in Kaiser, and BT standby seems to draw very little. I leave mine all the time, I loose about 5% battery overnight. WiFi is a completely different story, it's a power PIG.
[Tilt, TyTN II, MDA Vario III General] herpi:
I still disagree.

When bluetooth is just ON and not connected to any device it hardly consums power. (IMHO)

Do a simple test and let it on for a night sleep with and without bluetooth.

When connected to a headset or whatever it of course consumes.

Pls tell me the difference.,

I have had my TyTN II since Tuesday the 25th - so only 2 days now. I pulled the phone out of the charger at 6:50am this morning. I have WiFi turned OFF (only use at night when I am surfing while watching TV). I have BlueTooth off. I do have BB Connect installed and running with 1 BES account and 3 BIS accounts. I was on the phone for maybe 5 total minutes so far this morning - and I surfed for like 10 minutes via EDGE on the way to work. I do have SPB Mobile Shell 1.5 installed, but from what I read it doesn't effect battery life. I have the unit set to shut the screen off after 2 minutes....and my LCD brightness is at like 70% or so.

With all this - as of 10:35am this morning - I am already down to 75% battery. At this rate, the phone will be dead before 5pm....! Not even a full day.

Man - I hope this gets better because I can't run my life with phone plugged in half the day just so it will last me!
[Tilt, TyTN II, MDA Vario III General] herpi:
1. Are your phone settings on: (phone settings/band/network type) GSM, auto, or WCDMA?

2. Not fully clear to me: is you phone going on standbye automatically?

Have no experience with the Blackberry stuff however. But still curious.

For me "GSM only" was the solution, even with MSN Live messenger on-line hardly any battery loss in sleep mode.

[Tilt, TyTN II, MDA Vario III General] millab:
I just bought a trinity 3 days ago, and i have the same problem. i'm returning it tomorrow!

dead battery at midday, left charging for 12 hours. only reached 70% charged and getting very hot. When it did get to 100% previously, the phone would be flat in 12 hours with no use. I suggest you return the phone. seems either a battery issue or the phone itself.
[Tilt, TyTN II, MDA Vario III General] Bratag:
Do you leave your phone on the charger all night? If so DONT - nothing screws up a battery more than that. Since my last post I ran my battery all the way down to like 20% then fully charged it. Battery life much improved. I charged it on the wall charger and left it alone during that time - no turn on no nothing.
[Tilt, TyTN II, MDA Vario III General] danielherrero:
I had that issue too. The only solution (for me) is keep the device in 2g (GPRS) and switch to 3G only when you need bandwidth (web, tv, etc). And go back to 2g after using it....Now battery lasts 2 days. Before, with 3g, only 8 o 9 hours.

[Tilt, TyTN II, MDA Vario III General] adamzeit:
herpi and Bratag - thanks for the responses:

1) Both my Band settings are set to "Auto". I should just set the first one to "GSM" "? What about the second one? I am in NY (Long Island) but 3G isn't wide spread yet - so I hardly get 3G anyway and I will not be concerned with accesssing 3G until it rolls-out more.

2) I have "Backlight" set to turn off after 2 minutes - which 'locks' (sort of) the device and I have to hit the Power Button to re-activate the screen. Is this what you are referring to - or is there something else I should look for?

3) Yes - I plug the phone into the wall charger by my bed before I go to sleep - and I don't pull the plug out until I wake up the next morning.

Thanks again guys - I appreciate the follow-up help with this.

[Tilt, TyTN II, MDA Vario III General] jomo25:
on #1, yes, set the first to GSM and leave the second one as Auto. And only when you want to use 3G, set the first one back to Auto.
[Tilt, TyTN II, MDA Vario III General] herpi:
I fully agree, and of course, but you probably have that as standard setting: Battery/advanced/ turn off device if not...etc etc.

GSM only was my solution also. No more battery drain, even with MSN messenger AND bluetooth on continuously. Day and night!

Changing it only to "auto" when:

1. I need a lot of internet browsing.

2. I do not want to close MSN messenger when calling. HSDPA for example lets you use the phone and keeps the internet ( MSN messenger e.g.) running.

But maybe this is old news for you.....

[Tilt, TyTN II, MDA Vario III General] adamzeit:

Hey all,

having the same battery drain issues here thanks for the info on switching to GSM only, I just did that will see how it goes and then post my findings back here.

[Tilt, TyTN II, MDA Vario III General] unwired4:
Biggest drains are:

1) Wifi on

2) 3G on (and using for voice)

3) 3g on (and active data - eg actually surfing/emailing/IM-ing)

4) 3g on and hunting for signal

The battery drain on 3g is very high but thats the price you pay for having a mobile broadband device that can do so much - so as previous posters say - either top up your charge your device halfway through the day (USB lead to pc or car charger?) or turn it down to GSM if you are going to be away from power for a long day.

It was very similar for the Hermes.
[Tilt, TyTN II, MDA Vario III General] athanaso77:
There are many Kaiser owners that do not use 3G, wifi, GPS, camera, music player... but still face large problem with unexpected battery drain. The problem is Bluetooth!!!! If you have bluetooth on (for hands-free) for example... the battery power dissappears in just a day and before the night comes!!!!

I hope for a cooked ROM that will solve that serious issue that we did not face with other HTC devices.
[Tilt, TyTN II, MDA Vario III General] PerfAlbion:
I think this isn't necessarily good advice. Li-Ion batteries don't actually work as well when they're discharged to relatively low levels, work best when they're charged often, and suffer corrosion if the charging units overcharge them. The advice you're giving is more appropriate to NiCADs, which suffered from memory effects if you didn't significantly discharge them before recharging them. I leave my TyTN II on it's charger all the time without any negative effects, and do so with anything I own that's got a Li-Ion battery.

If you want positively great coverage of battery technologies and issues, hit Battery University. The information ranges from highly technical to very simple.

I suspect that the OP actually has a defective battery with one or more bad cells, myself.
[Tilt, TyTN II, MDA Vario III General] AndyNJ:
i'm sorry, i've got a total n00b question...

i'm also having some battery drain issues. how do i change what bands the phone uses as many of you have suggested doing?
[Tilt, TyTN II, MDA Vario III General] RemE:
You need to install a different comm manager, one that has a "3G" button. Then you can allow or disallow 3G operation as needed. There are comm manager cabs in the Kaiser Cabs sticky.

Bluetooth does not suck the battery nearly as much as any other radio in the Kaiser, mine consumes 4% overnight.

Battery, the Kaiser and all other cell phones with a 3volt lithium battery, have only 1 cell in them. Lithiums are 3v per cell. In normal use I'd keep them charged, they all use "computer" smart chargers to stop charging the cell when full so leaving it in on the charger is perfectly safe and good.
[Tilt, TyTN II, MDA Vario III General] AndyNJ:
I found the "band" tab under "phone" in the settings. i changed the first drop down to "GSM" instead of auto. then under the connections tab, i opened HSDPA and unchecked the box to allow it.

that should help, right?
[Tilt, TyTN II, MDA Vario III General] RemE:
I believe it will, the comm manager route just makes on-the-fly speed changes easier.
[Tilt, TyTN II, MDA Vario III General] Bratag:
I agree - conditioning the battery is technically not necessary for LI batteries however I have found that doing it 1-2 times at the beginning does in fact help. I normally charge my battery often as possible. I dont like to let it get below 50% as a rule. My point about leaving the charger on overnight actually related to heat. The charging process generates it and the battery is enclosed. One thing almost all web sites etc agree on is heat+LI = short lifespan.

http://en.wikipedia.org/wiki/Lithium_ion_battery#Guidelines_for_prolonging_Li-ion_battery_life

I prefer to leave my phone at 75% overnight that put it on the charge for many hours while I sleep when charging to 100% might take only 1hr.
[Tilt, TyTN II, MDA Vario III General] RemE:
OK, the real deal on lithiums is yes, they don't like heat, but, the smart chargers completely terminate the charge when full. The battery if low, would get a little warm from the charge but cool off when done. Most all of my lithium chargers/batteries are cold/cool overnight in their chargers.

Lithiums MUST have smart chargers, if they were to receive a trickle charge when full, they would physically swell and possibly burst into flames. They really are great batteries but are also the most dangerous when mishandled.

The absolute best way to store them is at 50% charge but for phones it doesn't matter, I say keep it full.

I've also found that on my Hermes and Kaiser that when charging on a PC with USB and active sync active, the phone is warm always I suppose because of the USB remaining active. Using a cradle charger, the phone does in fact go cold after it's charged. I don't leave mine connected to a PC.

Go to settings -- connections -- beam and uncheck it. This will improve battery life. This is when Bluetooth drains the battery. Hope it helps :)
[Tilt, TyTN II, MDA Vario III General] PerfAlbion:
I'm not trying to be snarky, so please don't read this as such. How do you know that it's helping? Unless you're doing some pretty involved testing, this is purely anecdotal and can't really be backed up. Even conditioning the battery and observing isn't particularly appropriate unless you normalize for usage, which could be quite different day to day.

My point is - your experience contradicts the engineers and scientists that study this, so perhaps it requires more than an opinion.

It's true that heat is an enemy of Li-Ion batteries, but the heat they're referring to is typically listed as well above 100 degrees Fahrenheit. If your battery is getting this hot, then the charger is malfunctioning and either attempting to deliver too much power or not stopping when the battery is full. Quality Li-Ion batteries all contain chips to manage charging to prevent the problem you're referring to. If you hit this page, you'll find that the typical safety circuit on a Li-Ion battery doesn't kick in until you get to 194 degrees F.

It's also worth pointing out that the Wikipedia article you linked to links to Battery University as a reference site.

That's a fine strategy, though I'd personally recommend aiming for a higher starting number. If you don't fall below around 70%, then it's typically not considered to consume one of the "charging cycles" the battery can handle in its useful life.

I'm simply saying that leaving a Li-Ion battery plugged in with a quality battery and charger will not have any adverse affects on the battery. While my TyTN II might be slightly warm to the touch, it's certainly not in a range where the heat will have a significant adverse impact. I do the same with all my Li-Ion batteries, and I get at least two years of life from them on average. Usually, the battery ends up outliving the useful life of the device...
[Tilt, TyTN II, MDA Vario III General] demigawd:
How did you do that? My phone always connects using 3G when downloading email, and stays on 3G unless I'm constantly turning it off over and over again. How did you set it up to only use 2G unless otherwise needed?
[Tilt, TyTN II, MDA Vario III General] bluetoothless:
I was connected to 3G more consistently with my 8525 and had better battery life by far. Could it be that in just searching for the 3G signal it is draining more juice.

Battery Drain is an Kaiser issue

Hi

All the stuff about switching off and on this and that is cinda stupid. Cause this battery drain was not an issue on the predecessor TyTn (hermes). And the only thing extra here is the GPS which clearly is not the problem (since it’s always off and people still experience the same battery drain).

I'm using “Auto, Auto, BlueTooth” and I have only one day worth of battery. The AE-Button battery monitor tells me the current flow of consumption. When the device is powered on it uses between 180-200mA. Right after display turn on the consumption is 6-10mA. So clearly something is draining the power way too much. My display is always emitting a very low dizzy sound. Even though I dim the display light, the power consumption is way too high. The AEButton apps tells me I have 6hours of charge left after a fully charge. And that’s not far from reality, Neither is it far from insane battery specs from HTC.

I do use the device frequently (because its so damn cool and the best phone ever made, except of this battery issue), but so did I use my previous TyTn frequently

My bet is that HTC screwed up the display, making it drain too much power.

The only problem with this theory is that some of you guys out there report 2 days of user before charging the battery.
