Extend My28’s Battery Life

My28 and the exclusive to Smart My28S are decent phones with a fast quadcore CPU but with small RAM of 512MB which causes slowdowns when the phone needs more memory for the running apps, the slow down happen when the phone automatically kill running apps to get memory space. The big draw back of the phone is not the small RAM but the small battery capacity. Here are some tips to extend My28’s battery life.

Small Battery

1450mAh battery may be good for analog phones but it is bad for smartphones specially those who have  a higher cellphone CPU. I have listed a few tips to extend your phones battery life which also applies to other android phone models.

Turn Off  WiFi, Bluetooth, GPS and Data Connection

Turn on your WiFi connection on only if you need it, this will drain a considerable amount of battery life. Bluetooth should only be enabled if you want to transfer files to and from your phone including listening music. GPS should be turned on only if you need assistance to located your location. Most Android phone have the GPS feature but lacks the GPS chip which causes to phone to drain power more due to rough estimates being done by the phone like connecting to all nearby towers to figure out your exact location. Data Connection should only be turned on if you have a good signal coverage. A weak signal/reception will force your phone to boost it’s signal capacity and drain your battery.

Disable Dual Sim or Use Airplane Mode

Dual sim android phones consumes double charge power, if you are only using 1 sim, turn off the dual sim support. Some android phones automatically handles the management of sims. If your mobile phone detects a single sim, it will automatically disable the dual sim support. On My28/My28s can’t handle this well so you need to manually turn off the dual sim support.

Lower the Brightness 

One of the biggest battery drainer is the LCD screen itself, if you are mostly going to use your phone in enclose spaces, turn the lights to the lowest. If you are going to go out in the open, turn your light higher to a readable lighting. Android phone screen have issues on open natural light causing the screen to look dim or blurred when hit by direct sunlight. The common error people make is to set brightness to automatic, this make look to be a fine choice but it was not. This causes your battery to drain faster.

Stop Installing Speed Booster

Most speed booster just issue force close commands to running apps. Closing an app in android consumes a lot of power and most of the time also consumes more memory. Android was designed to keep most used apps to run on the background and “hibernate” apps that are seldom used.

Install CM Launcher

There is always an exception, a properly configured CM Launcher on your My28/My28S prolongs your battery life for about 30%-40%.  It is a small and lightweight launcher that prevents apps from opening when they are not needed, the catch, this launcher eats up a portion of your phone memory and some apps may take longer to start.

      You need a phone with a good GPS, at least 1gb RAM (space where programs run), Android lollipop and at least Dual Core CPU with a decent video chip.

      You can get a phone at around P4,000 – P5,000 for non-popular brands. MyPhone my35/36 for P6,000-P7,000 or Acer Liquid series for P6,000-P9,000.

      Note, Pokemon Go works with Intel CPU but the app store was set to block Intel phones.

      If the RAM space is below 1gb (common for cheap phones), Pokemon Go won’t run perfectly.

      If you have a desktop computer, I can write a guide on how to play Pokemon Go on your desktop computer.

        A guide for desktop? That’s great.

        One last thing..

        Would you happen to know if it is possible to have Android upgrade for OPPO R1001? (From 4.2.4 to ver 4.4 atleast)

    Hi. I downloaded pokemon go on my my28, however it keeps showing me “gps signal not found” eventhough i already turn on the “location”
    I even downloaded gps booster but also tells me that gps is disable

    How can i enable the gps in my28 so i can use it for pokemon go. Thx

    • coderinthebox says:

      my28 have no GPS chip instead it uses a software base approximate location for GPS.

      my28 also have a very small RAM and before you can even open Pokemon GO (which is RAM and graphics intensive), your booster will be shutdown by the phone’s memory management.

      If you are lucky, your phone will be dead in 20-30mins.
