How long to charge Xiaomi 1S: a complete guide with tables and tips

The question of how much to charge Xiaomi 1S is asked by both beginners and experienced users of this smartphone. The fact is that the time of full charging depends on many factors: battery status, type of charger, ambient temperature and even the firmware version. Xiaomi 1S is a budget smartphone with a battery capacity of 1650 mAh, which under standard conditions charges from 1.5 to 2.5 hours. But why is the range so large? And how to understand that the battery is charged 100% without harm to its life?

Many people mistakenly believe that the longer the phone is on charge, the better. In fact, recharging is one of the main causes of degradation of lithium-ion batteries. In this article, we will analyze not only the exact charging time of the Xiaomi 1S in different scenarios, but also tell you how to extend the life of the battery, which chargers to use, and what to do if the smartphone does not charge at all or charges too long.

If you’ve just bought a Xiaomi 1S or noticed that the battery is going to go down faster, this guide will help you avoid the typical mistakes and save on battery replacement.

1. Standard charging time Xiaomi 1S: table by charger types

The Xiaomi 1S’s full charge time is directly dependent on the power of the charger (ROM).The manufacturer recommends using the original 5V/1A (5W) adapter, but many users connect the smartphone to more powerful RAM (e.g., from the Redmi Note or POCO) This speeds up the process, but it is not always safe.

Below is a table with real charging time under different conditions (tests were conducted on a battery with a capacity of 80-90% of the factory):

Note: If your Xiaomi 1S charges for more than 3 hours using the original RAM, this could mean:

• 🔋 Battery wear (capacity below 60% of factory capacity)
• 🔌 Charging port malfunctions (oxidation, pollution)
• 📱 Background processes (applications, updates, viruses)

To check the battery status, type in the dialer code ##4636##, then select "Battery Information." If the health value is below 80%, it's time to change the battery.

How to Charge the New Xiaomi 1S: Myths and Reality

With a new smartphone, the question often arises: “Do I need to fully discharge and charge the Xiaomi 1S before first use?” The answer is no, this is an outdated recommendation for nickel-metal hydride batteries. Modern lithium-ion (Li-Ion) and lithium-polymer (Li-Po) batteries do not require “training”.

However, there are 3 key rules that will help to extend the life of the battery:

⚠️

Note: If you bought a Xiaomi 1S bpd, check the battery first with the AccuBattery app (available on Google Play) to show real capacity and wear. If the capacity is below 1200 mAh, the battery is critically worn out.

Many users mistakenly believe that night charging is harmful.In fact, modern smartphones (including Xiaomi 1S) automatically turn off power when they reach 100%.However, if the phone lies on charging for more than 8 hours, this can lead to:

• 🔥 Overheating (especially if the ROM is more powerful) 10W)
• 📉 Loss of capacity due to microcharges (when the level drops to 99% and rises again)

Charge your smartphone to 100% without interruptions |

Turn off the network after full charge |

Repeat the cycle 2-3 times for calibration |

Avoid using your phone while charging.-->

3.Why does Xiaomi 1S take a long time to charge or not charge at all?

If your Xiaomi 1S charges for more than 4 hours or does not respond to the connection of RAM, the problem may lie in one of the following factors:

Hardware causes:

• 🔌 Micro-USB port is contaminated or damaged -- check for debris, oxidation. Clean with alcohol and toothpick.
• 🔋 Battery wear – if the phone turns off at 30-40%, the battery needs to be replaced.
• ⚡ Faulty charger – try another RAM or cable.

Programmatic reasons:

• 🤖 Firmware failure - perform reset settings (Settings) → Additionally. → Recovery and discharge).
• 🦠 Viruses or background processes – check your phone with an antivirus (e.g. Malwarebytes).
• 🔄 Incorrect settings of energy saving - disable the "Ultra-saving" mode in Settings → Battery.

⚠️

Warning: If the phone vibrates but does not charge when connected to the RAM, this is a sign of a short circuit in the port or battery.

For diagnosis, use the hidden menu of engineering settings:

1. Open the Phone app and type ##4636##.
2. Select "Battery Information".
3. Check parameters: Charge level (should increase when connecting the RAM) Temperature (normal: 25-40 ° C, if higher - overheating) Voltage (normal: 3.7-4.2V)

4.Optimum charging mode to extend battery life

To ensure that the Xiaomi 1S battery lasts 3-4 years instead of 1-2 years, follow these recommendations:

What to do:

• 🔄 Keep the charge level in the range of 20-80% – this reduces the load on the battery.
• 🌡️ Avoid extreme temperatures (do not charge in the sun or sub-zero temperatures).
• ⚡ Use original cable – cheap Chinese cables may not provide stable voltage.

What to avoid:

• 🚫 Playing while charging – this increases the battery temperature.
• 🚫 Charging from left-hand adapters (for example, from old Nokia or Samsung).
• 🚫 Storage of a discharged phone (if you don’t use it for a long time, charge up to 50% and turn off).

To automatically control charging, install the AccuBattery app (a free version available on Google Play).

• The actual battery capacity (in mAh).
• Charging/discharging speed.
• Battery temperature.
• Wear forecast.

💡

If you often charge Xiaomi 1S from powerbank, choose models with support for Quick Charge 2.0 and a capacity of at least 10,000 mAh.

5.How to speed up charging Xiaomi 1S without harming the battery

If you need to charge Xiaomi 1S quickly (for example, before you go), use these methods:

Safe ways:

• ⚡ Turn off the phone – when the charge is off, it goes 20-30% faster.
• 📵 Activate the aircraft mode - this turns off energy-consuming processes (network, Wi-Fi, GPS).
• 🔌 Use the ZU on 10W (2A) — redmi 4/5 fit.

Emergency methods (rarely used!):

• 🔥 Charging when the screen is off – reduces the load on the processor.
• ❄️ Refrigerate your phone – Put it on a cold surface (but not in the fridge!).

⚠️

Warning: Do not use Quick Charge constantly – this reduces battery life by 15-20% per year.

If you need to charge your phone up to 50% as fast as possible, follow this instruction:

Turn off the phone.|

Connect RAM to 10W (2A)|

Put your phone on a cooling stand (e.g. metal) |Do not turn it on until you reach 50%-->

Replacement of the battery on Xiaomi 1S: when you need and how much it costs

The average battery life of the Xiaomi 1S is 2-3 years (or 300-500 charge cycles).If you notice the following signs, it’s time to change the battery:

• 🔋 The phone will run out in 2-3 hours without active use.
• ⚡ Charging takes more than 4 hours, but the level does not reach 100%.
• 📉 When connected to the RAM, the percentage of charge “jumps” (for example, from 10% to 50% and back).
• 🔥 The phone warms up even with a small load.

Cost of battery replacement in service centers:

If you are replacing the battery yourself, consider:

• 🛠️ You'll need a plastic spatula, suction cup and screwdriver. T4.
• 🔋 The new battery should be of the same capacity (1650 mAh) and with a similar connector.
