Mobile Devices/Smartphones are very capable devices that pack all the functionality and power at reasonable price levels. However, battery life issues continue to become the major pain point that sticks out like sore thumb. Manufacturers want to stay competitive by adding high resolution screens, high-speed multi-core processor and large storage space. However, our smartphones need enough juice to drive it all and battery technology doesn’t progress fast enough, despite the already common availability of fast charging feature. Adding more mAh means larger battery size and many consumers don’t want to buy thick smartphones. The common trade-off has been associated with the slimness of the device and the overall battery capacity. Here are reasons why your smartphones have poor battery life:
1. Many apps running in the background:
Excessive battery drain may happen if apps are misbehaving. If we see a list of running background apps in our smartphone, it’s obvious why our device continue to bleed battery juice. Candy Crush Saga and Vine are known to cause repeated wake-locks. Social media and email applications automatically refresh themselves in the background, causing additional drain. When installing a new app, we should check whether it includes background refresh feature and if there is, we should be able to set it to manual, instead of only at automatic. It means that data will be refreshed manually when want to do it. Although we will miss out the automatic data feed, we will have improved battery life. If it is difficult to identify the problematic app, we could install GSam Battery Monitor to know which apps are using more battery resources. Once identified, we could restrict the activity of the app or find a more efficient alternative.
2. Photo management:
Many smartphone users installed Dropbox or Google Photos, with the backup feature enabled. In order to save battery life, we should configure the setting to enable the backup process only when the phone is being charged. However, these options are typically available only on Android smartphones.
3. Unusual app permissions:
With Android Marshmallow, we are able to check the permissions of the installed apps. As an example, it may seem unusual if a photo gallery app asks for a permission to use the phone dialler. In this case, we need to tweak the app permissions and disable those that we don’t need. This will save us a ton of battery life. However, we should know that denying permissions recklessly could cause our apps to misbehave; so we need to be careful. When installing an app, we should keep an eye on unusual permissions, especially the one that asks for our location information. The permission could be used to deliver relevant advertising messages, but it means that GPS feature will be engaged; draining our battery life.
4. Bad charging equipment:
It is possible that we are using faulty cable or slow charger. For optimum performance, we should use chargers that are rated for our smartphone model, preferably the one that’s provided by the manufacturer. However, even if we use cable and wall adaptor that is included out of the box; they could still be damaged. In this situation, we could be encouraged to use the low-cost, generic replica. We should know that low-power chargers and cheap cables could harm our battery. Incompatible charging equipments could reduce the retention capability of our battery. Often, people are forced to charge their smartphones using the USB port of their laptops and this could result in very slow charging process.
5. Frequent manual closure of apps:
Apple and Google continuously discourage users from clearing up recently opened apps too often. Recent Android and iOS versions are able to dynamically allocate resources for apps that run in the background. If an active app runs short on memory, some resources will be taken from background apps, without closing them. If we manually close these apps, they will need to be restarted again, requiring more processing and battery power. So, it is better to let Android and iOS manage available resources allocation.
6. Too many widgets:
Many smartphone users are eager to use tons of 3rd party customizations and widgets. If there are too many widgets on our homescreen, we could experience a fair share of battery drain. We should know that widg
ets like calorie burn calculator and step counters could use a lot of hardware resources. Some of these widgets may be created by incompetent add developer, causing additional efficiency problems. Widgets may also contain ads modules as the revenue source for the app developers. To save battery life, only use one or two widgets that you can’t live without.
7. Live wallpapers:
Live wallpapers are pretty and attractive, but they will cough away too much battery juice. On AMOLED displays, it is a good idea to choose dark colored or black background to save battery life. Wallpaper with vivid colors, sharp contrast and rich animation will cause the AMOLED display to drain too much power. LCD displays are less affected by selections of colors and contrast. However, on both displays; it is a good idea to avoid using live, animated wallpaper; unless we want to impress our friends for a short time.
8. Too many push notifications:
App developers often want to re-engage users by using plenty of push notifications. However, this feature can be a real offender; causing excessive battery juice bleeding. Some apps may send notifications almost each hour, causing phone to light up and consuming some amount of Internet data. We should check whether these notifications are really needed. WhatsApp and other instant messaging apps may also send notifications for each group conversations and they also need to be tackled as well. Groups that we are not interested in should be muted and any notifications from them should be disabled. With Android Marshmallow, we can long press the notification to turn it off.
