You can no longer count on reliability of budget smartphones or Android One

The story here is about my bad experience with a Nokia 7 Plus smartphone which is a certified Android One device.

I have been using Android over the last 7-8 years or so, and like every geek out there I was involved in flashing custom ROMs and tracking XDA forums for new builds. I even had one of the best phones suited for this purpose – The LG Nexus 4.

A small review of JBL E65BTNC

In 2016, I came across a nice deal for an on-ear headphone – The Motorola Tracks Air. It was selling on Flipkart for ₹2500. That was steal deal, considering the original price is ₹8990. I used it for on and off for quite some time but the on-ear type meant it started hurting my ears when using them for more than 30 minutes. So gradually the usage waned off and I stopped using it. Usually I do not buy new stuff unless the previous one I have is completely dead, this is especially true in case of electronics. Because of the online shopping deals it’s very easy to accumulate unnecessary junk. Just like that due to impulsive purchases without much thought I have a few electronic junk lying around which is in pristine condition not used even a single time.

In order to get rid of the Tracks Air headphones which I had, I tried putting an ad for it on OLX India site which is a famous marketplace for pre-owned stuff. I have successfully sold quite a lot of things on the platform and even bought a few. But for some reason people didn’t seem to be interested in this headphone at any price, so I gave it to someone I knew and didn’t have any headphone for free. At least something lying in my junk is useful to someone.

Maintain lead acid batteries regularly

Thursdays are usually maintenance day for the electrical power supply company in my area. So there was nearly a full day power cut. Luckily, I have a UPS so that sorts out the problem for 8-9 hours. The lead acid battery I use for my UPS is about 3-4 years old, and these being unsealed batteries they last long, really long if maintained properly.

In the past I have had one such battery last for a decade before requiring a replacement.

Unsealed lead acid batteries require two important maintenance activities:

  1. Topping up distilled water every 6 months
  2. Applying petroleum jelly / grease on the terminals to prevent corrosion

99% problems in electronics are related to power supply

My dad, who has worked a lot in electronics always says this one thing:

99% of problems in electronics are because of a bad power supply

Today, a real experience of this: In 2014 I bought a GSM signal booster to solve the call drop problem at home. It was working fine for all these 2 years, but since a few weeks the calls started dropping again. The booster had come with an 5V 1A adapter which powered it and I never switched off the booster. When I went to check it, the small screen on it showing the signal strength was blank and even after restarting it a couple of times it didn’t turn up again.

So I replaced the power adapter with my old Nexus 4 charger which can supply 1.2A at 5V. And boom, it works. Signal strength improved and calls are clear again. So always need to keep this in mind, whenever there’s a problem in electronics, first check the power supply.
