Full Battery Alarm Android App

[Replay Creation]

How The App Is Different:
It does not need to be re-arm again and again. Once installed, app will automatically sound an alarm each time mobile phone's battery is fully charged. Other than ringtone alert it also has a option of vibration alert so that one can receive notification while charging phone during seminars/meetings etc.

Overcharging your mobile phone can damage the phone's battery. There have been many incidents in past where the mobile phone battery exploded into pieces due to overcharging. The harm caused by the battery explosion can't be ignored and thus Full Battery Alarm™ app was built to avoid any such loss. Full Battery Alarm™ App sounds an alarm as soon as mobile phone battery is fully charged.

Full Battery Alarm™ prevents your mobile phone battery from being overcharged. In today's busy schedule it is very hard to check the battery status again and again. Full battery alarm™ is an unique app which notifies the mobile phone user when their mobile phone's battery is fully charged.

Full Battery Alarm™ has three different type of notification settings. You can select your favorite ringtone or can choose vibration or light blink alert if you are in a meeting. Install the app in your mobile phone and launch the application. No need to re-arm the app again. It will automatically sound an alert once the battery will be fully charged.

Features:

· No need to re-arm the app again

· Ringtone Alert

· Vibration Alert

· Light Blink Alert

· Adjustable Volume of ringtone

· User Friendly Interface

· Notification if app is closed by task killer

· Multiple language support (Any language can be added on request)

· Remaining Charge time

· Automatic start on reboot

Sorry but I have to dispute your claim that a phone battery can be overcharged.
Do you have any sources?
Instead of sounding an alarm why not just make an app that cuts off charging when the battery is full (which happens to be built into every phone)

Hi, thanks for reviewing the app.Yes of course most of the smartphone cuts off charging when the battery is full but the phone's again starts charging the battery once it drops below at certain point. For most of the phone's it is set to 99% battery percentage. Because of this, your phone's battery undergoes a On-Off cycle which actually hampers the life of a battery.
So it is always advisable to unplug the cable as soon as the battery charges and to charge your phone again when the phone has been used for a while.

I disagree that it hamperes the lifespan because say 100 charges of 1% equals a whole charge of 100% so with a phone that's never turned off, it balances out becoming equal.
I'm not trying to shoot down your app btw. If anything it might do it's bit to save the planet

Funky is right, there is no way trickle charging has any negative impact on cell lifespan.

The only thing that can harm a Li-Ion cell are deep discharges.

None of this is true.

The turn on point for charging on most every phone is around 95 to 96%.

There is no on/off cycle for a battery.

You're making it sound like a light bulb.

There's charge and discharge. Batteries are made to discharge, rechargeable batteries are made to charge.

By the way, lithium batteries don't trickle charge - the safety circuitry in the phone does indeed turn off charging once it's at about 100%.

Thanks for the expert reviews. I'm not challenging anybody's review as all are expert in their respective fields. There have been many incidents in the past which support the fact that over charging the phone's battery is not a good habit.
Anyways, we are gonna add some more useful widgets in the app to increase its usability. Thanks!

Thank you for citing articles that are VERY WELL KNOWN here and support what I said earlier. From Battery University -

"In lieu of trickle charge, some chargers apply a topping charge when the voltage drops."

(In the case of Android devices, that's not just some, it's all - there is no harmful trickle charging.)

"Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge (maintenance charge) would cause plating of metallic lithium, and this could compromise safety."

(Exactly as I said - safety circuitry cuts the charge when full. Most of the rest of the article describes saturation, which doesn't happen by design.)

The second article goes on to explain that heat is the enemy - that's absolutely true.

The danger on any Android device to battery lifetime is deformation of the metal structures. On a phone that's not being abused, once you put it on a charger and leave it alone, temperature ought to drop during charging and then hit a steady state.

Here's a picture of that happening on my phone -



Well below body temperature. A few years ago I showed battery temperature rising to just over 98°F while being held as opposed to just sitting on a table. I'll try to find those shots for you although I make no promises, it's been a while.

And because no priority is given to updating the battery percentage once the battery is at full charge, it appears that it's at a steady 100%. And that's not true. Once off of the charger, and after a few minutes of settling in, the true charge level is updated.

This leads to the popular myth that Android is broken, the battery drops 5% in 5 minutes - and has led to a booming business for battery enhancers that do absolutely nothing worthwhile.

Precisely because batteries are not being charged into saturation, the actual charge shown after removal from the charger will be within the switched range I mentioned earlier.

Maybe you own some device that behaves differently, I couldn't say.

As heat - as happens from a badly configured phone or as may occur during the deep saturation you claim is happening - is the real enemy - have you thought about a temperature alarm?

I'm sure you'll agree that a battery charging at 130°F at 90% is in far greater danger of losing lifetime than mine is fully charged at 80°F.

Anyway, that's just a suggestion. Along with the other criticisms, you do as you think best.

I'll keep an eye out for your other apps, I'm sure that this won't be your last. I do applaud you for caring about battery lifetime and offering to help!

PS - ignore the 5d 9h value in the graph above, I've obviously zoomed in to just the last 7 hours or so of my current history.
