General :: Store Unused Cell Phone Battery?

Jul 3, 2012

I'm about to retire my trusty old Epic 4G and whats the best way to store my battery on it. I will be removing it but I'm not sure whether I should store it fully charged or half way charged. If I remember correctly, I read somewhere that you should store your battery with 50% charge for it to have some life if you ever need to use the phone months or a few years time. Storing it fully charged can pose a threat due to the battery blowing up?!?! Not sure if this is correct or not. What to do to preserve your unused batteries in your old phones?

HTC EVO 4G :: Cell Phone Transmitter & Battery Drain

Jun 3, 2010

A cell phone is a transmitter just like a radio tower, and higher power is required to send the signal farther. Every modern cell phone automatically adjusts its transmitter power based on reception. Fewer bars means faster battery drain when you are using your phone. Switching to 2G will not necessarily save battery. If you have a 3G tower nearby, then your battery will last longer. And if you have a spotty 4G connection, you'd best plug in, or don't use it. However, given equal signal strength, a 4G signal is MORE efficient per byte than 3G.

General :: When Battery Dies Phone Goes Into Downloading Packages / Entering Store Mode

Aug 10, 2013

Every time I let my SIIX batt die the phone states "downloading packages" and "entering store mode". A picture of an android shows up, the only way for me to get my phone to work again is by doing the following:

-Plug the phone in and let it charge a bit
-Unplug the phone from the charger and take the batt out
-Put the batt back in making sure it stays unplugged from charger otherwise it goes back into store mode

Only then will my phone go back to normal and charge....

HTC Incredible :: Battery Draining Really Fast - Cell Standby And Phone Idle At 36% Each

Aug 6, 2010

Just yesterday my phone was getting more than 14+ hours of battery. Now it's draining really quickly even when I'm not using it (I left it on while I was asleep). It's not facebook because I already downloading the fix and rebooted. My "time without signal" is 0% so I don't think that's the problem. I did download Quickpedia yesterday but a quick search tells me that's not the problem either.

The only other thing I did differently was switch from ADW to LauncherPro yesterday, but if that was draining the battery wouldn't it be under Android System and not standby or idle? Regardless, I switched back to ADW just to see if that works

General :: Asus Fonepad Battery Drain In Standby Due To Cell Radio

Sep 20, 2013

I recently purchased this Tablet cum Phone Device (Asus Fonepad) in India. I found this device very impressive with decent battery backup along with great standby time. Everything was allright. In morning I found heavy battery draining during standby.

Next day I uninstalled that Black market application and Uninstalled Exdialer with all downloaded themes. I got full signals and everything was working fine. But the Battery Drain in standby remain same. I observed the situation till next two days. I searched to forums and did following things:

1. I made factory reset to my fonepad. which was haviing 4.1.2 Android after updating through OTA. Which remains same after Reset.
2. I didnt install any other applation
3. I turned of all battery comsuming services like GPS/ Location reporting/ Data/ Wifi/ Uninstalled Google Play Service Updates etc
4. Installed Wakelock detector, Better Battery Stats etc All are showing that phone goes in deep sleep no prblem but Wakelock detector show that Cell Radio wakes up so much time when phone is on sleep mode. Default Battery monitor of Android Showing "Mobile Data" as most battery comsumer.

One thing I want to mention here the device is supportive to mini sim only. I was not having mini sim so I went to market and mobile shop keeper cutted my Sim to adjust into that slot and it woked. I was using same sim from Day first. It's Vodafone INDIA.

I have not rooted nor flashed anything from my fonepad. I am reached to the conclusion that There is some problem with Exdialer installation and applying new/old theme combination to it which made me device with no signal. And now The Cell Radio has been changed which is attempting to achive something in standby mode. Which is causing heavy battery Drain. Standby time is reduced to almost 15-16 Hrous

General :: Battery Drain By Mobile Network Signal / Cell Radio?

Jun 15, 2012

I've ported a Hero ROM to a HTC Magic.Here's my problem:

Problem: There's a great battery drain when you're connected to the network (no data but just mobile network for calls/SMS)

Ported ROM: Sandwich Deluxe 4.0 .

Original ROM: Hero ROM

Kernel: carz-2.6.34.4 (fast and stable)

The mobile network drains battery.I'm not in a low signal-area. Everybody who uses the ROM has a drain.I'm using a 2.x.x instead of a 3.0 kernel for an ICS ROM, can it be that this mismatch creates the drain?The phone displays a singal strength of 0dBm 97 asu. (Not normal?)

What doesn't cause the problem? In airplane mode there is no drain at all. So it is unlikely that some apps causes the drain.Wifi, GPS, sync, ... are all disabled.

What do you expect from xdamembers?

- Confirmation if the kernel is the issue of the drain. If not, I would like to know which files (in ROM) are responsible for network signal.

Android :: Is Phone Automatically Kill Unused Tasks?

Jul 16, 2010

Maybe I am misunderstanding something but I believe Android is supposed to automatically kill "unused" tasks after a while. Is that correct? I own a Galaxy S and I see that I still have in the running tasks list some apps that I haven't used for more than 18 hours. And these taks do not make any kind of auto sync, they communicate with the network only when used actively. Am I misunderstanding something?

HTC EVO 4G :: Cell Standby Demolishes Battery

Jul 29, 2010

I charge my evo while I'm sleeping. Last night I went to sleep with it at 100% and woke up 10 hours later to find that I had lost 50%. Battery indicator told me that it was 48% cell standby and 48% phone idle and only 2% Android system. Is this usual? I didn't know just leaving my phone on the table would kill so much.

My current idea is to purchase a used pay phone and somehow connect it to my cell phone so that I can place and receive calls. I know of devices that can be connected to landlines but they require their own phone number and I don't want to add a line. Are there any devices that I could use Bluetooth to send my call into the landline phone?

General :: Removing Languages And Unused Stuff?

Jan 28, 2012

I want to create a light rom for my RK2818 tablet. I removed lots of apk's, and it works fine. Now, I want to delete the unnecessary languages and dictionaries from the keyboard (LatinIME.apk).

How can I do it? Can I simply remove the folders like resaw-da with Total Commander (compression set to 0)? I want to keep English and Hungarian languages only.

I'm also interested in more tips to speed up this unofficial cyanogenmod 2.3.7 rom, because this old chinese tablet with 256mb ram is only used to watch movies and browse the internet. I've already updated the hosts file with the adfree version, and removed the following apk's:

ADWLauncher.apk (replaced with LauncherPro)
Bluetooth.apk (no BT in this device)
Calendar.apk
CalendarProvider.apk
Camera.apk (no cam...)
CMStats.apk
CMUpdateNotify.apk

[code]....

Can I remove any of these? I want to remove everything wich is not important.

HTC Incredible :: Cell Standby - Battery Killer

Apr 30, 2010

I was just wondering if anyone had the same issue as I do, with about 44% of my battery use coming from the notorious call standby.

I heard some speculation that this is akin to the issue with the Eris 2.1, so it would be solved by the Airplane Mode trick, but I have not found any results favoring that remedy.

Android :: Cell Towers & 6 Hour Battery Life?

Sep 18, 2010

Got a really strange problem. I am in Vietnam using MobiFone service. About 3 months ago something changed overnight and my battery went from 20 hours to just a 6 hour battey life. After a week I did a factory reset but the same. Took it to HTC in Saigon to be tested but they said no problem YET when I was there battery lasted longer. The problem was in only in Can Tho where I live UP to this month when the problem is now in Long Xuyen. I travel, to Cambodia a lot and usally when I leave Can Tho Battery life is better. I am now in Cambodia and battery life is 40 hours on a CamShin SIM. For a test in Can Tho I went to a phone shop and used a Vinaphone SIM for an hour and got a 40 hour life. This is a joke! Is there any application that can control the Radio or at least tell me what's going on? I tried a few but they do not say anything different between Vietnam or Cambodia. MobiFone did something but refuse to tell me anything. Back of my G1 with 1.6 is cool now but in Vietnam back of phone is very warm. Tried to reflash the Radio but phone will not let me. I rooted but still it will not let me. think I must load a new recovery program.

HTC Droid Eris :: Battery Draining - Cell Standby And Idle Are 36%

I tried doing the Airplane trick...I am not sure this is the 50% issue others have mentioned because when I go to view my battery statistics, it doesn't show the 2 lines of information like it did before (i.e, 50%), but my phone idle and cell standby are Both hanging around 36%...seems kind of high in my opinion.

Motorola Droid X :: Battery Life Is Terrible - Shows Display At 93% And Cell Standby At 7%

Aug 2, 2010

First off, I read these forums like every day for 2 months (nearly drove my wife insane!) leading up to the release of the X. Stood in line and bought one in the store on the 15th. Had nothing but iPhones until now - loving my DroidX!

BUT

As of right now my battery is down to 60% after having been unplugged (when I unplugged I was at 100%) for 1hr 46m 9s!

It shows display at 93% and cell standby at 7%.

I'm running smart battery mode, auto screen brightness, not that many widgets, and I rooted it and have autokiller running on Aggressive.

Do I just have a bad battery? And if so will Verizon (or Moto) give me a new one?

Motorola Droid :: Wifi On - Cell Signal Weak - Fast Battery Drain

I think I figured out why sometimes my Droid stays on for 1.5 days and sometimes after 6 hour of just being idle the battery is drained.

When wifi is turned on an connected to a network, the cellular signal is way low and it just drains the battery.

Android :: Getting Cell Signal Strength For Current Cell Vs Neighboring Cells

Jan 6, 2010

I'm writing an android application that collects cell signal strengths.I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths.To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback.It works, but not very well.It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers.I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better.The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths?It seems odd to me that the functionality of the neighboring cells is better than the current cell.

General :: Battery Meter Bug During Charge Makes Phone Think Battery Is Dead

Nov 9, 2013

I have a sprint GNex. I just started having this problem recently (but before the 4.3 update). I plug my phone in overnight and at some point in the middle of the night an error occurs that make the phone think it is off the charger and has a fully depleted battery. The battery level icon shows no charge and if I pull the phone off the charger it immediately says it has to shut down due to a low battery. However, as soon as I turn it back on it is back to normal with a full charge.

General :: Phone Shows Up 3 Times In Google Play Store

Mar 26, 2012

I was just surfing the Google Play Store on my laptop, just browsing some apps, when I noticed my phone HTC ADR6425LVW showed up 3 different times when it prompted which device to download the app, too.

I am rooted, I have the HTC Rezound and a couple days ago, the desktop Google Play Store showed 2 different versions of my phone. I didn't really make anything of it because I exchanged my phone for a new one during the 14 day return period. Why this would happen, unless it occurs when I flash new ROMS. But I've flashed at least 6 ROMS over the course of at least 20 different times. Would this cause warranty issues if I try to have a replacement done if something happens to my phone?
